I am looking for a new locking folding knife for use at work, and as a spare for when i am out in the woods. I want a very secure lock, and a thumbhole instead of a stud as i find them easier with gloves on. The Benchmade Griptillian seems to fit my needs but i am not keen on hollow ground blades. Can any of you suggest anything else that fits the bill in the saame sort of price range please? Preferably blade length between 3" and 4", with a tip up pocket clip.
