I have one of those that I got from Laguiole southwest, years ago. Love the knife, the only complaint is that everytime I let it close on it's own, the inside of the spine hits the blade. Over the years it caused a flat spot on the blade. I usually sharpen it out.
I also have a Fontenille Pataud. I prefer it over the Chambriard. The Fontenille seems to be better finished.
