I received my first ever Microtech about a week ago. Black and green DOC. At first, it was very stiff out of the box. Flipped with lots of effort, just wasn't that smooth. And the lockbar tension was a bit much. I had ordered the pivot and scale screw bits from Blade HQ, so I was able to loosen the pivot a bit, but then the blade centering was off. So, I tightened up again to center the blade. Blade grind was perfectly symmetrical, and the edge very, very sharp.
I have found, that for some reason, on bearing pivoted knives, the way to smooth them out and make them flip like lighting is to hit the pivot with a heat gun. This made a drastic improvement on the DOC action, even with the pivot tightened back up. It has also worked on my 2 Brous Silent Soldier Flippers, and my Guardian Tactical Helix. Just enough heat, and the blades rocket out of the handle, and almost close on themselves when unlocked. This and using reel oil on the pivot. I use Abu Garcia Reel Oil on mine.
Comparing the DOC to the Guardian Tactical Helix, the Helix wins. Marginally better clip, much lighter knife overall, and after the heat treatment of the pivot - smoother/faster flipping.
