Im a noob still, so don't take my ramblings as gospel. You won't find too many people around here who will praise CRKT. They are experienced and have their reasons. All I can do is give you my humble opinion
The M16 has a liner lock. Not the best lock around, not in the axis lock league, but it does the job. Since joining this forum I learnt a few tricks. So I went home and tried the spine whack test - lock the blade in the open position and smacking the spine of the blade on something solid, make sure you keep your fingers out of the path of the blade, just in case it fails - if you have a good lock the blade wont fold and the lock wont bind open. My M16 passed with flying colours. I ended up putting a few huge dents in my desk (use a mouse pad to prevent this). This is by no means a definitive test, but it does instill some confidence :thumbup: The M16 also has the LAWKS system - I have never used it or relied on it. From reading other members posts I determined the the LAWKS system is not really there to prevent lock failure, its there to prevent you accidentally pushing the liner lock into the unlocked position under heavy use.
An explanation of LAWKS - I little lever on the top side of the handle. When you engade it a little washer with a "tang" slides in place next to liner and stops it from being pushed all the way into the unlocked postition. Not much of an explanation, but you get the general picture.
I like my M16, a lot! Not as much as my Mini Grip, but I really enjoy carrying it. I like to think that my M16 is a medium use folder. Deffinately rugged enough for any daily tasks you throw its way. Although, Im not sure you can save the world with it
A word of caution - make double sure that you buy the AUS 8 version, most probably will have an aluminium handle. If it has a z behind the model number it is the zytel handle and most likely has AUS 6 or even AUS 4 steel :barf:
