Couple of months back, I needed a replacement EDC knife and got a Buck 112 Ranger auto opener. Been carrying it in a pouch on my belt daily ever since. Its blade has maintained razor sharpness w/o any attention from me, even though I find that I'm always using to open packages or cut whatever needs cutting. The auto open feature makes it a breeze to do those jobs where one hand is occupied by holding onto something.

Kinda pricey, but in this case I think I definitely got my moeny's worth.
