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.
Another new classic from Design Within Reach. The Japanese Weeding Knife ($40) is a dynamic blade used to dig small holes, uproot weeds or pot small plants. It's serrated on one edge, smooth on the other, with measuring lines on one side. Perfect for gardening or cutting up fools.
