Only knife I carry is on my leatherman, and it doesn't get sharpened much, as it usually is used to cut things that will dull the blade. Yeah, I can sharpen a knife to a paper cutting edge with a stone, but to be honest, I have better things to do with my limited free time, which I consider to be quite valuable. Like smoking cigars! If I'm smoking at home, the cutter is already there, right beside my humi, and if I'm smoking away, it's in the traveldor, along with the torch lighter with the built in punch. On the one hand, I should maybe upgrade my cutter as this one is a 3 buck benchmade v-cutter that came free with the traveldore. On the other hand, I've had it since Iraq 09-10, it still works great, and the price was right! Oh....and I eat apples with my teeth....:eyepoke:
