My Marlin( no not the gun maker) 3 1/2 " lockblade with thumb assist & pocket clip, holds an edge, easy to sharpen, all for $15 at Ace Hardware, I never leave home without it...
Top is SOG Twich II and is my favorite, mine is great but I have seen shabby models. Next is CRKT Endorser, it is very nice. Then Onion D2 when things need to be fancy. Lower is CRKT M16, which is horrible in the pocket and I have been abusing it regularly but it just won't die. The lowest is a Tac something off Amazon for $7 that puts expensive knifes to shame. In the background is my Mora rainbow that are X mas gifts from me this year.
Haha, a bunch of enablers. When I was a kid I used to collect "rocks" -- a nice, cheap and informative hobby. Knives? Not so much. Amazon prime is turning my nest egg into a great collection.
