I'm a HUGE Spydero fan, so the Manix jumps to mind, with the Manix 2 right up there.... but without my Leatherman "kit" (Wave, Fenix. 3/8 firesteel, firestraw, Hood's Woods whistle), I have to go with my old Puma Gamewarden... superior (IMHO) to the Buck 110..... both a sharp sturdy blade and a functional saw. If we are only talking single blade, I might do OK with my newly delivered (15 minutes ago !)
BM111H2O; this thing is a ROCK, axis lock, N680 steel (corrosion resistant), and is shaped to excell at virtually everything except stabbing... sorry, no pics, since I am apparently too old and/or stupid to figure out the process...
Getting old is a real bitch, until you consider the alternative.... (Anon)
