I had one and will never own another. I had several problems with it. First, the tip broke twice within weeks of purchase. I've read forums that say this is very common. The next problem involved the hinge. There is a (plastic/nylon/teflon?)bushing that fell apart. That left the hinge sloppy side to side and the opening wasn't as easy. The final problem was the thumb stud fell off. I used JB Weld to put it back on but it came out again a couple of months later. I finally pitched it.

Here is what I did like. I love the blade shape. It just worked well for me. I also loved the handle. It was thin and slid into my pocket well.
