Been carrying a knife every day for 30 years or more ... my favorite is a Ka-Bar 3-inch Dozier Design folder ... also carry a Spyderco Byrd or a new knife I picked up from Russell's, a Boker ... quit carrying a Kershaw Chive a while back when the safety failed, the blade opened a bit in my pocket and I almost cut off a finger ... 8 stitches to put the tip back together ... I use whatever I'm carrying every day for something, and I guess in a pinch, they might be helpful against BGs if the gun runs dry and I missed ...
"The gun has been called the great equalizer ... It insures that the people are the equal of their government whenever that government forgets that it is servant and not master of the governed." --Ronald Reagan
