I love OTF's. I recently spent about $200 on a Microtech UTX-70 expecting an exceptional knife. The knife seemed great until it broke. The button to extend /retract the blade floats up and down and does not control the blade. I wonder if all Microtech's are as cheaply made. I bought it from BladHQ.com. On monday, I'll find out what their customer service can do. Anyone else had problems with Microtech otf's?
