I carry a Spyderco Paramilitary 2. easily one of the absolute BEST knives on the market. It was my first knife, I bought it for myself last Christmas. I am now NEVER without it, I even take it to the bathroom, and trips to the kitchen in my boxers at 3 am. its spendy but worth it, I just luckily found some in stock yesterday and ordered 2, one for me and one for my dad for Christmas. seriously, buy one. If you dont want to spend that much the Spyderco Manix 2 comes in at a close second place. you can find them for around $70
Once you start carrying a QUALITY knife. you won't ever leave your bedroom without one. I use my knife EVERY day.
