Multipurpose Knife. Unlike other snap-blade knives, Tajima’s Driver Cutter has a stiff tip on the front edge of the blade sleeve that can be used to drive slotted screws, remove staples, or pry open paint-can lids. According to the maker, the “driver” tip is made of 1-mm-thick tempered steel and meets JIS standards for screwdriver-tip hardness. The knife comes with three 8-point blades (two are stored in the handle) and costs $8; a pack of 50 replacement blades costs $16. Tajima Tool, 888/482-5462, tajimatool.com
