I have been carrying a Spyderco Delica (Lightweight) for the last 6 years...every single day. The only problem I had with it was, the original plastic molded pocket clip broke when I cut a corner too close in the hallway and the clip snapped on the edge of the wall.
I sent it back to Spyderco and they milled off the remnants of the molded clip, and put a metal clip in it's place held in place by three screws. They also cleaned it, and resharpened the (full) serrated blade....all at no charge to me.
If for some reason, I forget to clip it in my front pant's pocket, I feel naked without it.
It has served me well for a myriad of applications including bottle opener. However, I don't reccomend that due to the wear and tear it does to the plastic handle.
Whenever someone in my family needs a knife to open or cut something, I'm always....ALWAYS the first one to offer the blade...while the rest of them are too busy opening thier Gerber Multipliers, Leathermans, or even folding knives they keep in a belt holster.
