I haven't found an MTech that looked like it would last long. A friend of mine at a local Big 5 says they get returned fairly regularly, for everything from faulty components to crappy build quality. I've had a couple, and I killed 'em just for fun. (They now live in the dead knife bucket in my garage.)
I could be wrong, but if I remember correctly, MTech ripped off one or more of Todd & Tanya Begg's knife designs. They approached them & asked Todd to design a model for them, and he said no. Later, looking at the MTech photos of some of their new models, and then photos of Begg's knives, the ripoff was obvious.
I love the look of Begg's designs. I can't abide ripoff manufacturers like MTech. There are too many other good manufacturers out there with great economy designs, like Spyderco, CRKT, Buck, just to name three.
