Kershaw Cryo. Durable, good looking, fits nicely in the small jeans pocket, and has assisted open. Hands down best pocket knife I've owned and it's less than $30 on Amazon and easily beats the $110 CRKT I snapped a tip off of.
Recently gave carrying a switchblade a try. For starters i have tried the cheaper Blue Horizon from swordsswords.com. Really liked the experience. Now I am thinking about investing a little more and will try PRO TECH GODSON TUXEDO from myswitchblades.com (fingers crossed). Living in Dallas sure has its perks!!
Lately I've been carrying a CRKT M16 ... It keeps a nice edge and is nice and light. Before that my every day carry was a kershaw leek, but it accidentally went through the washer and dryer one day & the blade popped open somehow and the tip snapped off.
