What in the hell are you going to do to a folder to make the lock fail??
regular work. I have had this happen twice where I was actually cut. Both liner locks, and price wise both the same price as my Recon 1 (old Axis lock design).
My older brother was unfortunate enough to actually require surgery on the tendon in his right thumb. He was cutting rubber! Trying to pierce rubber, and bam. Also with a name brand liner lock.
I have had many times where a lock has failed in normal use most times nothing happens.
So I am one, who won't buy a knife I don't trust the lock on.
I have no problem using a slip joint, but I want to know that the knife I am using will behave like a non locking knife before I use it.
Either the Triad lock, or frankly, even the older Ultra lock (Axis lock) will be stronger over all, and certainly withstand shock much better.
The Emerson will be a nice knife.
I do like the Aus8 steel just for ease of sharpening and generally it is a decently tough steel. I have been using mine for 10 years with no problems or issues.
Find and example of each, and hold them and if possible play with the locks and use them then make your decision.
I just don't feel as confident with liner locks any more. (there are many many great ones, which I would have no qualms about using, but if I am buying one with my money, Frame lock, or Axis lock, or Triad lock, heck, I wish they would release a higher end Ram lock like on the pocket bushman.......LOVE that one. Just upgrade the steel, and make the handle more attractive, and I would buy another one in a heart beat!).
