A hard year 2020 has passed, everybody was in any way connected to the changes due to Corona. As the year 2020 luckily has passed by, we are happy to announce another update for the future. After several years of work in the form of research of the history and furthermore experimenting with the Purple-Red La Lune Stones we are happy to announce that we actually try to re-release the purple-red „La Lune“ Stones.
So far I can only tell that we are doing this with the greatest respect of the ancient Producers and Suppliers because we appreciate and love their work, their product and the Trademark as it was created many years ago.
The re-release will be done with strict rules we set up to ourselves, this means how we source the material and how we deal seriously with our idea.
Our research and our approach was always to do this as team work. Practically speaking, not only „US“ four did the work, everybody adding a small piece in some of the Shaving or Razor Boards might have set up another piece of the puzzle, so in the end we could reach the goal where we are now standing…
Right now we have to discuss and decide some serious topics for the re-release. As you all might know that is not an easy task..we hope that we can come up with another Update soon.
The final product will be marketed under the registered Company from Nicolas.
Frequently Asked Questions on the LA LUNE Hones (FAQ)
Do the “LA LUNE” Razor Hones need to be lapped? And how?
Yes, the stones should be lapped. This could be done with some easy working tools (fex. Siliciumcarbide powder on a flat surface or wet and dry sanding paper) or with so called diamond plates from the well known companies like Atoma, DMT. Normally you start with coarser grains like (100-200 and afterwards you follow further steps towards 400/600/800grit to a maximum of 1000grit). Lapping in a higher grit ist most likely not needed on slate stones to receive a flat surface. Check that there are no more scratches within the surface. Best way would also to chamfer the edges, the LA LUNE Stones are normally sold with fully chamfered edges.
Are the Stones used with the delivered slurry stone?
The delivered slurry stone can actually be used, but it’s most likely used in the pre-finishing phase. You should know that the original vintage stones were used as plain finishing stones. The supplier F.G.B.C. (F. Ghelfi, Birolleau & Cie.) sold these stones as oilstones. This has been annouced in their Bulletin de Guarantee that the stones should be used with oil.
Is it allowed to use the stones with oil ? Or should this be avoided?
The stones do not need to be used with oil, but doing tests in concerns of performance showed that these slates are very dense and compact. So its no problem to use those stones with oil and later with water again. Our testting results show that with the usage of oil a finer polished edge is was created then using water. Also the shave itself after using oil on the stones seems to better perform. The shave felt more balanced and smooth then the one when water was used.
Are there other possible honing solvents which can be used?
Yes there is a variety of possibilities to try out. Its possible to use a water-glycerin mixture, a mixture of water and dish soap or even soap foam. Also there are many different types of oils which can be used. This is all fun to play, just try out and see what happens 🙂
What are LA LUNE Stones are made of? Whats their composition?
The Stones are a very fine and compact type of slate. Slates of that type exist in comparable compositions on other parts of our World. They are quarried fex. in the US (Purple Vermont Slate) or in England UK (Purple Llyn Melynllyn) .These slate varieties were created under near identical geological conditions, this results in a near looking appearance and in acomparable performance. The green inclusions in all of these three types of slates appear from wherever the stones come from. The composition is comparable with many other different natural stones.

Ein hartes Jahr 2020 ist vergangen, alle waren in irgendeiner Weise mit den Veränderungen durch Corona betroffen. Da das Jahr 2020 zum Glück vergangen ist, freuen wir uns, ein weiteres Update für die Zukunft bekannt zu geben. Nach mehrjähriger Arbeit in Form der Erforschung der Geschichte und des Experimentierens mit den lila-roten La Lune Steinen freuen wir uns euch mitteilen zu können, dass wir tatsächlich versuchen, die „La Lune“ -Steine erneut auf den Markt zu bringen.
Bisher kann ich nur sagen, dass wir dies mit dem größten Respekt der alten Produzenten und Lieferanten tun, weil wir ihre Arbeit, ihr Produkt und die Marke, wie sie vor vielen vielen Jahren geschaffen wurde sehr schätzen und lieben.
Die Neuveröffentlichung erfolgt nach strengen Regeln, die wir uns selbst auferlegt haben. Dies bedeutet, wie wir das Material beschaffen und wie ernsthaft und seriös wir mit unserer Idee umgehen.
Unsere Forschung und unser Ansatz war immer, dies als Teamarbeit zu tun. Praktisch gesehen haben nicht nur „WIR“ vier diese Arbeit erledigt, jeder, der ein kleines Stück in einigen der Rasier- oder Messerforen ergänzt hat, hat möglicherweise ein weiteres Stück des Puzzles ergänzt, sodass wir am Ende das Ziel erreichen konnten, an dem wir jetzt stehen.
Im Moment müssen wir einige wichtige Themen für das „Neu auf den Markt“ bringen diskutieren und entscheiden. Wie wir alle wissen, ist dies keine leichte Aufgabe. Wir hoffen, dass wir bald ein weiteres Update hierzu erstellen können.
Das finale Produkt wird später unter der eingetragenen Firma von Nicolas vermarktet.
Frequently Asked Questions zu den LA LUNE Steinen (FAQ)
Müssen die “La Lune” Steine geplant werden und wie sollte man diese Planen?
Ja, die Steine sollten geplant werden. Dies kann man mit einfachen Mitteln machen (z.B. Siliziumcarbid Pulver auf einer glatten Oberfläche, Nassschleifpapier) oder über sogenannte Diamantabziehsteine der bekannten Firmen wie z.B. Atoma, DMT. Üblicherweise startet man mit einer gröberen Körnung (ca. 100-200 und steigert sich dann über weitere Stufungen 400/600/800 auf maximal 1000 hoch. Mehr wird üblicherweise auch nicht benötigt um eine ausreichend glatte Oberfläche zu erhalten. Es muss darauf geachtet werden, dass sich keine Riefen mehr auf der Oberfläche befinden. Zum anderen sollten die Seiten entsprechend abgeschrägt sein (im Idealfall wurden die Steine so ausgeliefert).
Benutz man die Steine mit dem mitgelieferten Anreibestein?
Man kann den mitgelieferten Anreiber durchaus verwenden. Üblicherweise wird dieser aber kurz vor der Abschluss bzw. Finishing Phase verwendet. Man muss wissen das dieses Steine historisch gesehen als reine Abschlusssteine eingesetzt wurden und der damalige Inverkehrbringer F.G.B.C. (F. Ghelfi, Birolleau & Cie.) diese als Ölsteine verkaufte. Im Bulletin de Guarantee wurde festgehalten das die Steine mit Öl verwendet werden.
Dürfen bzw. Müssen die Steine mit Öl Verwendet werden?
Die Steine müssen nicht mit Öl verwendet werden, dennoch haben unsere Versuche gezeigt das der Verwendete Schiefer sehr dicht bzw. kompakt ist. Das heißt, dass es eigentlich ohne Probleme Möglich ist die Steine mit Öl zu verwenden und später wieder mit Wasser. Unserer Erfahrung nach erreicht man durch das Verwenden von Öl eine feinere und bessere Schneide als wenn man Wasser verwendet. Die Rasur nach dem Abschluss auf Öl wirkt nochmal ein wenig ausgeglichener und sanfter als wenn man Schleifschlamm und Wasser verwendet.
Aus was bestehen die LA LUNE Steine?
Die Steine bestehen aus einem sehr dichten und kompakten Schiefer. Schiefer dieser Art existieren in ähnlichen Zusammensetzungen auch auf anderen Teilen der Erde. Sie gibt es Beispielsweise auch in den USA (Purple Vermont Schiefer) aber auch in England UK (Purple Llyn Melynllyn). Diese Schieferarten entstanden durchgängig unter fast identischen geologischen Bedingungen, dies führte dazu, dass sowohl Erscheinung als auch Performance sehr starke Ähnlichkeiten aufweisen. Die möglicherweise auftretenden grünen Einschlüsse gibt es bei allen dieser drei Schieferarten, egal woher die Steine kommen. Die Zusammensetzung ist ähnlich wie bei bei vielen natürliche Steinen die folgende.

1. F.G.B.C. = Ferdinand(o) Ghelfi, Birolleau & Cie. “Manufacture & Montage De Meules, Pierres a Aiguiser et a Polir” Production & Assembling of abrasive wheels, sharpening stones and polishing stones.The company was founded from Ferdinand(o) Ghelfiin 1903, which then existed besides the company from L. & B. Ghelfiwhich was under control of Belle. The following changes are documented: F. Ghelfi & Cie., 7 Rue de Charlot, Paris (1916/1922) F. Ghelfi & Cie., 47, rue de Saintonge, Paris (1933) – relocation F. Ghelfi Birolleau & Cie., 47, rue de Saintonge, Paris (1974) change of company name and owner.
Besides these changes there are predecessor companies which for have a close connection to F. Ghelfi & Cie. I created a overview of those companies which you can find on the first part of the story here:
In concerns of my researches and to the predecessors companies its impossible to miss the connection to Italy. Doing more research of the Italian family names “Bardotti”, “Giovannacci” and “Ghelfi” i found a lot of evidence to the old towns Pontremoli, Mulazzo and Montereggio (Mulazzo) in the historical region Luningiana. All of the families are well bonded together during many centuries which makes it somewhat complicated to get their connection easily together.
During the winter time it was very cold and the people suffered from hunger, many inhabitants had to sell goods on the streets. Many left their home and families and went down the Emilia-Romagna or the Lombardy. They had to strife their life as street dealers and they sold icons/holy images also musical instruments and razor hones
Luckily Jethro (Fikira)was interested to create a more detailed interpretation about the connection of the families and people being involved into that business during the centuries. That’s why i will leave out “too detailed” information and focus on general issues and pictures.
3. Old Pictures from the Store F. Ghelfi & Cie. at 7, Rue de Charlot
During my research i found a old picture from the store of the brothers Ghelfi (ital.: fratelli, the brothers were Carlo, Constantino, Ferdinando, Lorenzo and Jean-Baptiste).The picture was taken from the times where their business was at 7, Rue de Charlot, Paris. Also today the distinctive building structure can be seen.
Here are some newer pictures from the old location of F. Ghelfi & Cie. at 7, Rue de Charlot, Paris, one is an actual shot, the others are from vintage postcards which i bought:
Here are some newer Google Street View pictures from the old location of F. Ghelfi & Cie. at 7, Rue de Charlot, Paris:
Here are some newer Google Street View pictures from the old store at 47, Rue de Saintonge, Paris:
4. The Trademarks and Logos from F.G.B.C.
Actually there have been several “trademarks” or “main products”where logos have been created to promote the products sold on the market. They show up partly on their own, sometimes combined on the products. These were the following:
Letterhead “La Lune”
F.G.B.C. in a circle:
Moonface , “Special Stone only for Good Razors”, Straight Razor and F.G.B.C. in a circle
Moonface in a rhomb “Pierre La Lune” exiger La Marque F.G.B.C. (print from old envelope)
Pierre La Lune a Faux (print from old envelope)
Moonface in a square “Ne`demandez pas, l’une ou l’autre, mais…LA LUNE” “Don’t ask for one or the other, ask for….LA LUNE”
5. The quarries from F.G.B.C.
This topic is more or less the most un-researched within the history of F.G.B.C.and its predecessors companies . All quarries which were under position of F.G.B.C. have been listed and documented on the old invoices and letterheads. Up to date it looks like that none of those quarries has been extensively researched and more or less only a bit or no information is available. Those were the quarries named on the letterheads:
La Nouvelle, La Vaûte, La Parisienne (Gare Merviller-Vacqueville)
Neufmaison, La Boulaye (Gare Pexonne)
Béménil-Bas, Bréménil-Haut, La Parisienne (Gare Badonviller)
Its possible that there is a connection between their Trademark “La Lune” and “Luneville”.In near range of Merviller (Quarry of the Birolleau Family) Chateau Luneville is situated. So probably the use of the moon symbol is grounded on some personal experiences and memories.
Other approaches were made in France, so it is told that down Merviller (Lorraine) desert like conditions were existent in the past. Because of these conditions fine sand deposits combined with iron oxide built up very fine stone layers.Also there is an entry about a quarry named “Carrière de grès Birolleau” down in Merviller which might be the quarry were the fine sandstone for Grinding wheels had its origin.
6. Steige the origin of the fine red razor hones ?
Within the research i also asked Mr. Wilson if he would ask back some of the geological departments in France about the red fine razor hones sold as “LA LUNE”. Within this research we got a reply from the University of Nancy, department of geology. Actually Steige was mentioned as a region where these stones might have their origin. Further more research revealed that near Steige sharpening stones seem to have been quarried, but no more details were known or documented.
Another type of slate stone known in this region is a schist type named “Schiste Lie de Vin de Steige”. The stone itself just from its chemical composition shows good properties to be a sharpening stone. It contains 59,3% quartz (SiO2), 22% aluminum oxide (Al2O3) and 7,3% iron oxide (Fe2O3). So if we ever can find a connection to the fine razor hones ? We’ll see in future!
7. Products and Services from F.G.B.C.
F.G.B.C.’s business was not only the quarrying and selling of the stones. They also focused on technical services in terms of building up complete machines of grinding stones.
Here is an older price list from the competitor company as it was running under L. Belle:
Besides these two core businesses they were importers of stones and abrasives from different countries all over the word. Probably they focused on different businesses to offer a wider range of products and services, or to offer combined solutions on certain special applications.
They sold the following products: Arkansas and Washita Stones Turkey Oil Stones(Pierre Du Levante, Pierre Du L’est) Razor Hones “LA LUNE” Razor Hones “SPECIAL STONE FOR GOOD RAZORS” other razor hones / sharpening Stones
They also sold abrasives like silicium carbide, corundum, big grinding wheels made out of emery or sandstone (white, grey and red) and the fine razor hones which are known as “Pierre La Lune” and “Special Stone only for Good Razors”.
Besides these standard products they sold also razor strops and pastes to be used on the strops.
8. Razor Hones “Pierres a Aiguiser”
The razor hones sold as “Pierre aiguiser LA LUNE” are very fine razor hones which work the best when oil or a water/gylcerine solution is used. There are different interpretations within the razor scene how these stones should be used best. I yield the best results using glycerine/water mixture. The most important for me besides any interpretation is the proposal beeing made from F.G.B.C. as a seller of the stones.
F.G.B.C. neverannounced the stones to be used with water, they were always announced to be used with oil. Additionally the results with water are in my point of view not comfortable enough. Additionally the stones sold as “Pierres Belges de Lorraine et du Levant” which is the same slate as the purple La Lune stones should be used with oil
9. Qualities/Grades of the Razor Hones “LA LUNE” and “SPECIAL STONES”
Many of those stones can be found with rectangular stamps. If the stamps are still visible depends on the condition of the ink. Sometimes they are only visible very faint, sometimes you only see the letters because the areas around the stamp dries faster then the are were the stamp was printed on. The stamp itself shows a rectangular frame where the quality/grade of the stone is printed inside. The qualities were:
Some examples how those stamps do look like:
Normally those stones were stamped in the qualities with fine, very fine and extra fine.In January 2016 the first time a stone was sold on Ebay (Art. No. 221991500339, in size 17×4,2x2cm, 400gr.) which showed a comparable stamp. But this one wasn’t stamped as usual, it had a stamp with the wording “RAZOR HONE” in french “PIERRE A RASOIR”. I actually believe this was one of the newer stones which were sold from F.G.B.C. on the market.
10. “LA LUNE” and “SPECIAL STONE ONLY FOR GOOD RAZORS” from other Suppliers
Actually we are not sure if F.G.B.C. was the only seller of the fine “LA LUNE” and “SPECIAL STONE ONLY FOR GOOD RAZORS” slate stones. Its possible that the quarry owner also sold their products to other suppliers. So ist not clear up to date if the stones being sold from Manufrance (“Pierres Belges de Lorraine et du Levant”) or the Stones sold as “Pierre de L’est bleue” were sold from F.G.B.C./Giovannacci to other sellers or from the quarry owners directly.
Theory No. 1 – regional quarrying operations Especially on the french market serveral stones appeared which might get connected to the LA LUNE and SPECIAL STONES. Beside of those stones, there are often stones appearing without any stamps or any label. I myself got one in very unusual size (18x9cm) which seems that they have never been offered in these sizes officially. So my first theory is that they might have been sold also regionally which is nothing unusual compared to other types of natural hones.
The second theory is, that it might be that also F.G.B.C. just bought these stones from another company or quarry owner and sold these under their trademark. That could explain that also others might have bough these stones from the quarry owner and sold these types of stones under their own trademark.
The third theory is just that to a certain time the stones from F.G.B.C. haven’t been labelled or stamped! Its hard to prove those theories either combined or each standing by its own, but i think these are realistic theories. We will find out some time in future!
10.1. Pierre aux Croissants (S.D.P.)
We are today not sure if the stones labelled as “Pierre aux Croissants” are from a competitor or from a follow up company of FGBC. In concerns of this specific topic there are three theories up to date.
Theory 1: Societé de Distribution et de Promotion It showed an additional Logo with a Cirlcle and the shortcuts S.D.P. (Societé de Distribution et de Promotion) which could stand for a trading or distribution company or just a cooperation Partner who had the rights to sell their quarried stones under that Special Trademark. This has to be further more researched!
Theory 2: J. Delaunay Another trace is a company which had also a abrasive business in Paris. J. Delaunay also used a moon with a face in their Tradmark, so this might be a hint towards the Pierre Aux Croissants stones.
Theory 3: Connection to Severin Robert Droescher The Ghelfis had a longer business with Severin Robert Droescher (S.R.D.). So there is a chance that S.D. stands for Severin Droescher, right now i don’t know what the P could stand for.
10.2. Pierre de L’est Bleue
Also there are exiting stones with a totally different label, which was shown on Razorandstone from Modine. I asked Modine if i can show the pictures here, so here they are! This one was labelled “Pierre de L’est Blue”.
10.3. Pierre Aiguiser LA LUNE (T&T)
Those stones appeared in France with the typical La Lune Label. Additionally the stones as the wooden box showed another logo or trademark which is a double Flag with T&T.
10.4. Pierres Belges, De Lorraine et Du Levant
Those stones appear in a very nice wooden Box on top the Logo of MF Manufrance St. Etienne Manufacture Francaise D’Armes et Cycles. The ones i’ve seen so far re-sample the PURPLE LA LUNE stones. The sawmarks on the sides and the coloration makes it easy to identify thos stones as “LA LUNE” Stones.
Another documented case where stones have been officially mislabelled. Actually i believe that during these times the belgian Stones have been
11. A promise on quality! The warranty card, or the “Bulletin de Garantie”
F.G.B.C. was concerned to give a promise on the quality of their products, surely with the intention to convince their customers and create a long binding to them. The “Bulletin de Garantie” was delivered with the fine “LA LUNE” and “SPECIAL STONES”.
Bulletin de Garantie (french original) “La Pierre à huile à rasoirs naturelle “LA LUNE” ne peut être comparée à aucune autre. La finesse de son grain, sa pureté minéralogique permettent un aiguisage rationell et parfait, SANS DOMMAGE POUR L’ACIER. Une sélection rigoureuse de la matière première, provenant des meilleures carrières, une main-d’oeuvre spécialisée, utilisant des procédés millénaires font de cette pierre, LA PREMIERE MARQUE INCONTESTÉE du MARCHÉ MONDIAL.
N.B. – Soucieux des vos interests, votre fournisseur habituel vous conseiller a la marque “LA LUNE”. Seule pierre pouvant donner une satisfaction absolute. la Perfection dans la qualité !”
Warranty Card (englisch translation) “The natural oil stone for razors “La Lune” cannot compared to any other stone. The fineness of the particles and his mineralogical purity enables efficiently and perfect honing without any damage to the steel.
The careful first choice from the best quarries, specialized workforce and long established methods make these stones uncontested to the Number Ones trademark of the world.
N.B. – Soucieux des vos interests, votre fournisseur habituel vous conseiller a la marque “LA LUNE”. This stone will satisfy you. Perfection in Quality!”
12. Combination Stones “Combinaison Stone”
12. Combination Stones “Combinaison Stone” These are ones of the most interesting combinations stones being around. The stones were sold as “Combinaison Stone” under the article numbers AD12 (120x60mm) and AD20 (200x50mm). The stones are glued on a midsection of wood. Each side of the wooden box has a lid. Sometimes the lids were labelled with stickers or both wordings “La Lune”and “New Master Stone” were printed or punched inside of the lids.
13. Scythe Stones “Pierre a faux” made of Pierre Natural de Saurat
It seems that already in the earlier times there was a cooperation between F.G.B.C. and one of the older quarry owners who marketed the shale sandstones . The Quarry which is in the region of the Pyrenees down the Valley of Saurat. One of the more known Families running the business over three generations was the Cuminetti family. In 2006 the quarry was taken over form Mr. Alain Soucille who still runs the business to these days. The scythe stones appeared under the names of many different companies and under all kinds of different trade names and qualities.
As being a big importer of all kinds of sharpening stones also F.G.B.C. did import Arkansas Stones from the United states of America. Actually a lot of the companies dealing with sharpening stones and their supplies did this during the 19th century. They imported the stones and sold them on the local market under their own trademark. A very nice example appeared in 2015 and could be bought from a member of a German wet shaving board. Many thanks to Jörg (Jollo74) who did agreed that i can use this pictures here!
15. Other Stones made by F.G.B.C.
15.1. New Master Stone F.G.B.C. has, as many other suppliers and producers of abrasives, used the trends to produce and sell men made stones. These stones were made out of Silicon Carbide D48.
15.2. R.C. La Lune “Extra-Fine” Another “Special Stone” which was produced from F.G.B.C.. It reminds me a bit of the stones which have been produced from JGESand were named “Reform Brocken”. It is impossible to proof from which material/abrasives these stones were made. It is possible that for one of those sides dust from “LA LUNE” stones has been used.
16. F. Ghelfi, Birolleau & Cie. Prix Courant “Price List from 1974”
In 2014 FERDI (a member of Coupe-Chou Club and SRP) finds an old price list from F.G.B.C. from the year 1974 and shares it thankfully with the community. That was a really important step to become an overview of the prices and the products F.G.B.C. sold on the market.
After talking back to FERDI he wanted to support the Razorlovestones Project. I really wanted to show that price list here in that company profile. Also here a big thank you to FERDI for the permission to use the price list here !
17. Unknown Products During the last years several different products appeared which were not mentioned in the old Prix Courant / Pricelist from FERDI. There were f.ex. a “Pierre a Rasoir Naturelle LA LUNE” and “Double Face Extra Extra”. And the stone which i mentioned earlier with the ink stamp “PIERRE RASOIR”. Then there were those Razor Hones and Belgium Coticules with the double half moon labelled “Pierre Aux Croissants”.
Probably those products were sold by competitors or from predecessor companies of F.G.B.C.. Either those could have been sold in a time frame before or after the price list from 1974.
18. F.G.B.C. on the bigger trade fairs? Looking back from today we are sure that the Ghelfis’ and their predecessors companies were also active on the bigger trade fairs. This is visible on some of the older Letterheads, besides this there are some old entries. F.G.B.C. received the following medal:
1894: London International Exhibition, Crystal Palace 1895: London International Exhibition, Alexandra Palace 1904: International Fair in Florence, Big Price and Gold Medal
19. F.G.B.C. and Manufrance A french catalog company called “Manufrance”, which is still existent today, sold the Stones from F.G.B.C. during a certain time frame. So sometimes we find stones from F.G.B.C. which shows a MF“Manufrance Saint-Étienne” lable which was glued on the stones. Actually till today it wasnt possible to find a reference to these stones in the old Manufrance catalogues.
20. Collection and how to identify french stones These are most of the stones from my collection which i got from France. Buying stones in France will also bring up very different types mostly out of Europe. I experienced to find the following types of stones in order of their appearance:
Sometimes UK Slates in black and violet appear, also with a certain regularity Llyn Idwal Stones. So this makes it not too hard to compare the rare French Razor Hones with those types.
Sometimes it happens that a black/grey or grey/brownish stone appears. They show up a comparable glittering. In most cases these are a Pierre Naturelle de Saurat. These are also sold today with a lablel marked “Pierre à Menuiser”. These stones are less fine then the razor hones. I would rate them in between 4K-8K, some might be finer.
The main identifiers for the fine razor hones is in my point of view the type of metallic / bronze appearance of the stones. Talking about the violet/purple variant of the stones they will show up with a typical pattern and will have a bronze look. Talking about the blue/green metallic stones you will see that these show a metallic glittering in the light. The color ranges from a lighter grey-blue towards a blue-green, its also possible the greener areas appear in the stone. These show also the typical pockmarks which looks like little cracks (0,2-0,5mm) in the middle of these cracks you can see a darker spot.
