I like them okay, but the only time I ever carried one for serious was in Iraq, and it was only for use as a strap cutter. The Safekeeper II is neat, but since it has a double edge, it's illegal as hell in Texas, from what I understand.
There's a lot of puzzling illegalities here, now that I'm getting to know my way around. Bowie knives, for instance. You can legally carry a rifle, but you can't have a Bowie knife? Don't make a damn bit of sense to me.
