When looking for an OTF blade, it was easy to see why so many Microtech blades were on intergalactic backorder. The deploy mechanism makes a sound like a '65 Mustang door closing; perfect engagement. Fit and finish are amazingly well for a blade that is produced en masse. Really a great quality product, that I expect will last a good long time as my use is simply a daily carrying tool. I would not hesitate to buy again. Northwest Knives was easy and painless to deal with, plus they had some blades that "big box" web stores didn't...I order, they ship. Beautiful.
