I've added non-slip (skateboard) tape to the sides of 2 of my 3 Leatherman tools (didn't have #3 when I applied the tape, & just haven't gotten around to it yet). It makes hanging on to them much easier.
Cut tape to slightly larger than needed. Clean & degrease handles (alcohol wipe works), then apply tape. I used an old X-acto #11 blade to trim to fit, including contouring along cutouts, etc. Be aware that whatever you cut it with, skateboard tape is tough stuff, & will dull a blade. That's why the OLD X-acto blade.
It looks good, & works great. Should work on any multi-tool.
Also, be aware that it will slightly increase the thickness of the tool. It's not a problem in either a leather or nylon sheath, but could be an issue if Kydex.
