Charlie, I wish I had sent you this Sauveterre, but I must admit she definitively comes from someone else!

This is a Sauveterre named from the village of Sauveterre-en-Rouergue, a relative to the old "straight" Laguiole, built in the village as a "2 nails" (like an Opi, sorry, I never remember the exact name in English

Away please Aloïs!

) alledgedly from the XIIIth til the XVIIth cent.
It was revived in the late XXth as a slipjoint by Guy Vialis, who took the opportunity of a period TV series footage shooting in the village.
Since Guy Vialis retired and the workshop has been bought by an Espalion shop, then by Laguiole-en-Aubrac who recently re-released the 9cm and the 11cm.
ps I have an horrible doubt, your knife has no mouche... so she could very well be an Yssingeaux in fact ( was misled by the lack of bolster ). Next time I'll turn my tongue 7 time in my mouth...

This is a Canif Mongin (still in activity), one of the last Nogent's knifemakers. Exists in 2 length, 8cm and 10cm, from a single blade up to 10 tools, with a quite rare Fisherman's .
Mongin supplied many luxury brands, including Hermès and maybe Dunhill (irc). These are very well made (and sell accordingly) but "anoraks" say they're just a pale reflection of the high quality of former Nogent knives. The corkscrew might give a clue about its age.
