To us, a good pocket knife should be simple. No Mother of Pearl handles. No nail clippers. We just want a single blade that disappears into our pocket. Our current favorite is the Case Mini Blackhorn Knife ($18). Just 3 inches when closed, the knife has a lockback surgical steel blade and a Zytel handle that helps keep the weight to just 1 ounce. Case has been making knives in the USA for over a hundred years.
