If your techie person doesn’t own a multi-tool, consider getting them a Leatherman Wave Plus. At $100, it’s on the expensive side, but it does come with a 25-year warranty. It has 18 different tools, including pliers, replaceable wire cutters, wire strippers, knives, saw, spring-action scissors, rulers, a can opener, bottle opener, files, and screwdrivers. No matter what tech, electrical, or home-improvement problem your person runs into, your gift will be there to help.
