My grandfather has always carried a small blade. He has a Camillus one for as long as I can remember(about 12-13yrs), with about a 2.5" blade, slipjoint.
I recently(fathers day) got my father into carrying something else than his pipeknife(1/8" belly, 2", 3 tools+1 blade, tapper on one end). I picked up a cheap one for him. Maker unknown, but it has the Benchmade Butterfly on it, nothing else...
2.5-3" blade, spearpoint, thumbstud, rear lock
brass bolsters, wood handle, slightly oval cross section
Think I got it for $30...
he's converted, but won't buy anything more than $50... he used it for the last car repair, chopping the heater hose in one swipe.
Still can't get him to carry a multi-tool
