I'm not all that familiar with CR Knives so I thought I would employ you all for some infomation on the lock. Is the lock a liner lock with an added safety? Can the lock be adjusted for wear? Is the lock-up tight. My reasons for the questions is that I have had bad experiences with the liner locks on some moderately priced knives. (not junk from China). I don't want to mention names. Any info is apprecitated.
