It's a Fontenille from Thiers, probably from twixt 1920 and 1950, but can't pin it down just yet. Nogent style handle, (rosewod?) with rat tail tang, hammered/riveted at end, and a brass(?) bolster. Super agile, beautifully convexed, which makes for thin, thin thin). Cuts like a champ, and is way stiffer than I would expect. Nice on the stones, quick to sharpen, and has a nice DING sound to it.
Ok, Ok; what's the catch?, you say. Well, it does have some minor pitting in three places; otherwise she's a little champ for small dinner prep.
Sorry about the crappy photo quality, never did manage to get the poinšon with my cell!
