Hi: To me, a pocket knife is a tool, period. The fact that it might be used as a weapon holds no water to me. My automobile, my umbrella, the pen in my shirt pocket, my fist or boot or any number of other things could just as easily be used for a weapon as a knife could be used. Granted, a sheath knife with a six inch blade can also be used as a tool but is generally seen as a weapon, either offensive or defensive. A pocket knife on the other hand, with a blade of 4 inches or less, especially one with more than a single blade, should be thought of as a tool. Someone mentioned the Leatherman "tool"....that's just what it is, a tool. The fact that it has knife blades does not, in my opinion, make it a weapon. Knives have gotten a bad rap because they are mis-used by scum. In turn, the rest of the people who use them responsibly, must suffer.
My thoughts on the matter.
