I've owned a Leek since maybe a year after they came out - I forget when that was, but it's been several years. The sum total of my problems with it? I accidentally forgot to take it out of my pants once and it went through the wash and the dryer. The "slidelock" failed as a result of the heat in the dryer and the knife came open, which caused the tip to be broken off (maybe a millimeter's worth or so - just the very tip of the point). That's it. I ground the tip back to a point on my own, and wrote to ask the company to send me a new slidelock, plus a bill - they sent me four, for free. Oh, I almost forgot, I damaged the clip, as well, by catching it on a door frame latchplate and bending it out - again, I wrote to the company, asking for a price for a replacement part and they sent it, plus new Torx bolts to attach it, for free. Their customer service ROCKS. I've never been able to get it to take a true razor edge, but I can get it plenty sharp, and don't have much trouble keeping it there with minimal maintenance. It goes very nearly everywhere with me.
Overall, I've been VERY happy with it as a daily-carry utility knife.
