Leatherman tools are typically those huge foldable pliers that people slide into a holster on their belts. The Leatherman Squirt E4 is sort of like that except miniaturized for your keychain. Don’t be fooled by its small stature, the E4 packs in some really useful tools. This model in particular is for electrical jobs so it includes wire strippers, needle nose pliers, and wire cutters instead of standard pliers. Also included are tweezers, two flat heads, a phillips, an awl, a blade, a bottle opener, and a double sided file. Not too bad for something that goes with your keys. It’s available in three different colors: Gray (pictured), Blue, and Red.
