You don't carry a knife? I thought everybody here carried a knife. Word on the street is that a wife/girlfriend is usually fine with their significant other carrying a knife.
For some reason this reminded me of a funny story...
In my second year of college, on the last day of class we were having a pot luck, and the teacher was having trouble opening a sealed food package of some sort. She asked the class, "does anybody have a knife?"
Nobody responded. (The guy next to me was carving his name into the desk with a pocket knife just 10 minute earlier, and he was looking kinda nervous that the subject came up.)
After a brief pause, she looks in my direction and asks, "David, do you have a knife? You look like the kind of guy that carries a knife." Feigning outrage, I shot back, "just what is that supposed to mean?!" As I walked the knife up to her, she tried to respond with, "well you remind me of my boyfriend and he always carries a knife..." (looks at the knife I'm handing her, then nonchalantly adds) "... but his is smaller."
Did I mention this class was a psychology class on human sexuality? Let's just say the class enjoyed this exchange thoroughly.
Sorry for the derail, so I'll tie this back into the topic at hand...
ALWAYS carry a knife (unless you're boarding a plane or going into any other place controlled by metal detectors). Knives have innumerable daily practical uses, and could save your life.
I've carried a knife every day of my life since I was a cub scout. As soon as I got home from school, I put my knife in my pocket and went out to play. I honestly think I'm more likely to lose my cell phone, wallet, and/or keys than my pocket knife.
IMO, every able person should learn to safely use and train with blades as much as firearms. Knives are practical for daily carry, but swords are a lot of fun to swing around! If the zombies ever take over the world, there won't be unlimited ammunition. Will you be ready?
