My most used LM is hard to say I have used a Supertool, Supertool 300, Rebar (few different ones), a Wave and now a BO Charge + for the most part The Charge is mostly what I carry for work these days so I will put pics of it (Image removed from quote.)
Ironically my most used Leatherman looks amazing I used this in construction for years and it's still a beauty (Image removed from quote.)
