It's my usual EDC. I have a Kershaw Talon with a 1420ST blade; it's great for opening letters, cutting open boxes, cutting vine samplings, and all the small, detailed stuff like removing splinters or carving. The Talon also has Ti scales and teflon-coated bronze bushings and is as smooth and slick operating as many customs. It locks up strong and tight, the worksmanship is great and I paid $63 for it on sale!
I carry several other knives on occasion, but find myself always going back to the Talon. In fact, that's what's in my pocket right now.
