I have 3 pocket knives in daily use.
The 'Laguiole' (bottom) has a horn handle, and stainless blade. This is an indoor, all-purpose knife, that is used for general cutting, nail cleaning, and assorted DIY tasks. I'd rather bite the neck off a wine bottle than use that corkscrew.
The No 8 'Opinel' (center) has a beechwood handle and steel blade. This is in my pocket at all times. It's the knife I use outdoors; mostly when working up at Haddock's. It has no fears.
My latest acquisition, however, is the very new looking No 9 'Opinel' (top) which again has a plain beechwood handle, but this time with a stainless steel blade. This is the knife with which I now EAT.
It's possibly a dying tradition, but here in France, when dining out with country folk, one was always offered a plate, fork, and spoon, but rarely a knife; one supplied one's own. It's a tradition I've always rather liked, and still adhere to.
I'd never imagined myself buying a stainless steel bladed 'Opinel' (heaven forbid), or even a size 9. But, having thrown all caution to the winds, it's proved to be an excellent decision.
