My only M-Tech experience was a couple of multi-tool/locking folder sets. The multi tools seem okay, but they're bulky, hard to open, and not as well finished as my Leatherman products.
The folders were liner locks, and both were hard to release and close - though one was much harder than the other. The really hard one went to the trash bin.
The other needed to be sharpened. I was just learning my technique, and nothing sharpened up like that little guy. It took an amazing edge, but lost it after just a couple cuts. I cut some threads and didn't even feel 'em. I think the steel was so soft that I reprofiled it accidentally by holding too low and angle.
Anyway, after about 3 weeks of EDC one of the scale screws fell out. While I was at the store trying to locate the right size Torx bit, another one fell out, and I lost it. Rather than replace it, I just chucked the knife.
Replaced with a SOG, and have just gone up from there.
Anyway, I don't know what steel they use but if the same as the folder I expect it'll be tough (take some abuse without chipping) but probably not hold an edge all that well. If the ergos are okay and the price is right, just have fun with it!
