I'm sure this microbar works well. I have 3 liner locks, and never have I had lock failure. though I have never wedged my knife into anything either.
I think Joe's points are the following:
1) If Horus is wanting a knife with lock reliability being a promary criterion for choosing, microbars and loner locks shouldn't be considered. Mechanically speaking, an axis lock is much more reliable than a liner or a microbar. And,
2) If a knife is advertised as a hard use knife, it should be evaluated as such. Yep, Joe EXPLICITLY stated that one. Hard use knives get wedged into things. You should be able to get your HARD USE knife out of whatever it is stuck in, withoug the lock failing. As far as I am concerned, if a company advertises a product to do xyz, the product should do xyz.
Horus, if you are not prone to using a knife where it mught have to be twisted, a liner lock or microbar lock will serve you well. Mine have for a while now. If you are primarily concerned with lock failure, there are more reliable locks than liners and microbars.
Just get one and use it. If it fails, send it back to Microtech
Knife Fumbler, this statement reminds me of a statement that is on the web page for Eagle Industries:
"What good is a guarantee 4000 miles from the factory?" This statement, made by an aviator in the 160th Aviation Regiment, prior to Desert Storm, sums up what we are all about. Equipment failure at 10 feet AGL, in a hot LZ, or two seconds after you enter a hostage filled room, is not acceptable. Eagle Industries has been giving the professional operator the edge since 1982. The challenges of the Twenty-First Century will be just as real. That is why we work hard every day to develop solutions that have given this generation, and will give the professionals of tomorrow, the confidence that their equipment will not fail them.
I'd recommend not buying anything with the assurance that if it breaks, you can just send it back. Set out you rcriteria, do your research, and make a purchase. What good is any knife if it fails a user when he or she has some important HARD USE for it. Especially when a knife is advertised as being a hard use knife, but can't deliver. This goes for any product, not any particular product mentioned here.
