Every man worth his salt should have an Opinel Folding Knife. The made-in-France cutter has been in the back pockets of craftsmen, artists, farmers, and chefs for generations since 1890, and looks all the better as the blade oxidizes and the wooden handle wears. It's super portable, since the blade folds back into the handle when not in use. Opinels are suitable for everything from cutting sausage or cheese at a campsite to clipping kindling for a fire to cutting twine and tape off a package. (Pablo Picasso purportedly used his to chisel away at sculptures.) [From $8; opinel-usa.com]
