Now youre talkin. As a mechanic my 3 1/2 inch folder is as important as my right hand. I use it for evberything from opening parts boxes to cutting zip ties,stripping wire, prying open access tabs,cutting belts and hoses etc, you name it,it comes out of my pocket 10 times a day. A 3 1/2 inch,3/16 thick,7/8 inch deep,full grind, half serrated blade of 154CM with a 4 1/2 inch skeletonized handle in a fixed blade version is what ive been looking for for years. A lightweight,strong,edge holding,un-intimidating tool hanging on my belt right next to my LED maglite is what the best mechanic in New England needs. WOOF!
