When I was a lowly grunt I carried a sheath knife, a folder, a swiss army and a leatherman. Ok, maybe a wee bit of overkill there. Lately I am carrying a bare bones officer SAK and haven't found anything it really can't do, altho there are things I wouldn't do with it, like pry.

OTOH - My BOB has a woodsman pal, a leatherman wave, a gerber Command II(smaller boot sized knife, single blade but top edge is serrated for 2 inches, out of production at this time) and a SAK outdoorsman. And a small pry bar. And an E-tool.

When the fecal matter hits the air movement device, I want to have a selection so that I have the right tool for the job handy. Isn't that really what it's all about.
