I have had my M/A Elite for about a month and have been very pleased. I usally don't like to carry such a large knife, but this one is very light and rides nice and low in the pocket of my jeans making it a joy to carry. The action is super smooth and the microbar lock seems to be very strong. I haven't tried a spine wack test, but the locking bar is very thick and fully engages the blade so I don't imagine it would fail easily. As far as the blade itself, man does it cut. I have the current production grind that reminds me a lot of my Sebenza (not as much belly though). Edge holding of the 154 cm blade seems to be pretty good. Not quite the BG 42 of my Sebie but the SE did not cost nearly as much either. IMHO, the Elite is a great daily carry knife if you can get away with a knife that has a 4" blade.
