For most of my life I've carried a Swiss Army pocket knife. A friend, Carmen (the guy Harry helped
buy the Ruger SR1911), introduced me to the CRKT knives. They open with a 'flipper' at the base of
the blade, and can be opened and closed with one hand. They are *not* a switchblade!
I thought I'd have a rough time not having Swiss Army knife with the screwdrivers, etc., but I've
found I don't miss the tools much at all. Here's the one I've got.

Love it.
