Why are these knives, and microtech knives in general, so hard to find!? I've literally searched everything under the sun to find an ultratech but there only seems to be a few makes/models available. Does microtech only produce x-amount a year and when theyre gone theyre gone? Or did I miss the memo that they just aren't made any more? If anyone has info on where to find IN STOCK ultratechs, please pass it along!
