Many Leatherman tools include a small screwdriver blade, although some newer models have a bit driver with multiple screwdriver heads, instead of separate screwdriver blades. The profile for this tool varies slightly on each Leatherman model.
The Leatherman small screwdriver is usually about 2mm wide, 1mm thick and 25mm long (1/16" x 1/32" x 1"). It works well for driving small flat-head screws, or for very delicate prying of small things. This tool is the one that is most often abused: many airport-confiscated Leatherman tools have a small screwdriver tip that is bent, twisted or broken. Use it with care!
