IG marking or A.I.P.C.L. certificate: what does each one tell you?

Two proofs, two different questions

Anyone buying a Laguiole knife today may come across two things that both sound like proof of authenticity: a small engraving on the heel of the blade, referring to the geographical indication "Couteau de Laguiole", and an A.I.P.C.L. number with a certificate of authenticity behind it. Hence the question that keeps coming up: which of the two is the right one?

The answer is reassuring: they do not answer the same question.

A statement of place and an identity record. Both are valuable, and together they are worth more than either on its own.

What the IG marking achieves

The geographical indication "Couteau de Laguiole" is the result of a struggle that lasted decades. It was homologated by the French trademark office INPI, filed by the Syndicat des Fabricants Aveyronnais du Couteau de Laguiole, and from the following year an independent certification body has been awarding the marking to the houses that meet the specification. How that road unfolded and which workshops carry the marking today, we have written down in detail: The IG "Couteau de Laguiole" explained.

What this marking means for a buyer can be said in one sentence: the place name on the knife is no longer a claim, it is a verified statement. That is a big step for a word that was freely available to everyone for decades. We have the greatest respect for it - this protection was won by people, not handed out by administrations.

What matters just as much is what a geographical indication does not say, and that is no criticism, simply its scope:

• It says nothing about the one knife in your hand, but about production in a workshop. It is a property of the manufacture, not a record for an individual piece.
• It does not accompany the knife through its life. Whether the knife is given away, inherited or sold, the engraving stays the same - and it knows nothing of that change.
• It says nothing about knives made outside the area. A Laguiole knife made by hand in Thiers is not a counterfeit; it simply may not appear under the protected designation. Why this is so clear to us can be read in Thiers and Laguiole: the two capitals of the French knife.

What the A.I.P.C.L. certificate achieves

Our register begins exactly where production ends. A knife we have examined receives a number, and that number has its own permanent page on aipcl.com. It holds the photographs of this knife, its data, the workshop it came from - and its owners in chronological order.

The three properties that matter:

• The number stays with the knife. Not with the dealer, not with the first buyer. When the knife changes hands, the new owner is recorded and the story continues. A certificate that stayed with the seller would be worthless.
• The record can be verified online. A printed document can be imitated, an entry in the register cannot. Anyone wanting to buy a knife second hand can be shown its authenticity before paying.
• The owner decides who may see it. By default the page is closed, so that nobody can piece together other people's collections from the numbers. Opening it, or showing it to one specific buyer, is for the owner alone to decide.

And our register knows no regional border. It covers Laguiole workshops from all of France, from the Aubrac as well as from Thiers. What counts for us is not the place name on the blade, but that a human being in a French workshop built this knife and stands behind it by name. Which houses these are can be seen on the page The workshops.

Where our register ends

Said just as openly: we are not a public authority. The A.I.P.C.L. is a private register, kept by people who examine Laguiole knives, work with workshops in France and stand behind it with their own names. We do not award geographical designations, we cannot forbid anyone anything, and we issue no official attestation.

What we can do is what lies in the nature of a register: identify a knife beyond doubt, record its origin in a particular workshop and keep that record verifiable for decades. That is something other than a geographical indication - and it does not replace it.

The differences at a glance

Who issues it?

The IG marking: an independent certification body, on the basis of a specification homologated by the INPI. The A.I.P.C.L. certificate: we do, after examining the knife and in cooperation with the workshop.

Where can I see it?

The IG: in an engraving on the knife itself, on the heel of the blade. The certificate: in a number belonging to an entry in the register, which can be looked up online under Find a certificate.

What does it apply to?

The IG applies to production within a defined area. The certificate applies to a single knife, whether it comes from the Aveyron or from Thiers.

For how long?

The engraving has been in the metal since the day of manufacture and remains unchanged. The record grows with the knife: every change of owner is added to it.

And when the knife is sold?

The engraving passes on with the knife, without anyone having to do anything. For the certificate, the new owner is recorded - that is the step seller and buyer take together, and it is the reason the proof will still be worth something in twenty years.

What if my knife has no IG engraving?

Then it is very probably entirely in order. The marking is new, the vast majority of genuine Laguiole knives in the world are older than it, and knives from Thiers do not carry it as a matter of principle. The reverse holds just as much: whoever has it holds an additional confirmation, not the only one.

Why the two complement each other

It becomes clearest with a knife from the Aubrac that carries both. The engraving says: this knife was born where the name comes from, according to established rules. The record says: it is this one piece, from this workshop, and today it belongs to you. Whoever knows both for their knife holds the most complete proof of authenticity that has ever existed for a Laguiole.

Our second focus: the community

There is a part of our work that touches examinations and numbers only indirectly, and it matters to us just as much. A register puts things in order. A community carries them.

On this portal the workshops from Thiers and from Laguiole stand side by side, not against one another. That is a deliberate choice: the two towns carried this craft through two centuries together, and whoever plays them off against each other has not understood the history of the knife. In the ranking of the workshops you therefore see both origins in one list, separated only into large houses and individual knife artists - because a manufactory with many hands and an artist working alone do not belong in the same column.

Added to this are two occasions in which the workshops are not the subject but take part:

• The LAGUIOLE CROWN. Once a year the collectors themselves elect the most beautiful Laguiole knife. No jury, no editorial team: the people who buy, collect and use these knives are the ones who vote. Voting takes place in several classes, so that an everyday knife does not have to compete against a collector's piece, and anyone with an account may vote. For a workshop this crown is something no catalogue can replace - it comes from the buyers.
• The Laguiole Way of Life. Once a year people from all over the world send in photographs of their knives in everyday life. The finest reach the final, and every finalist receives a knife as a gift. These knives are donated by the workshops - they get nothing in return. They do it for the community, and we name them on that page, year by year. For that we thank them from the heart.

And because a collection only comes alive through its stories, collectors show in the private collections what they have found and why this particular piece. Every knife in them carries an A.I.P.C.L. certificate of authenticity - which closes the circle between the sober record and what a knife means to its owner.

What we take from this

If you have a knife in front of you and want to know where you stand: look for the engraving on the heel of the blade, and ask for the A.I.P.C.L. number. One tells you something about a place and a specification, the other about this piece and its path. If one of the two is missing, that is not yet a bad sign - if both are missing and nobody can name a workshop, it is time to have the knife examined.
