CRKT C/K Pro LAWKS question

[MW740]

Hey guys, I've been lingering for a while and so far been able to answer any questions by doing a search, but here is a new one. I recently purchased a crkt c/k pro large and have a question about the lawk system. The liner lock engages solidly on the blade and there is no play in any direction, but the lawks does allow the liner lock to move halfway off of the blade when pressure is applied to the liner lock, which in turn allows the blade to move in the closing direction a few thousanths of an inch. I don't believe that this is a safety factor, it is just slightly annoing. If this is a common thing with the crkt knives that use the lawks system than I will not be concerned, but if it is not then I'll be sending it in to CRKT. Thanks to anyone ahead of time for any input.

This is normal in all the CRKT knives that have the LAWKS feature. If you engage the LAWKS, you will still be able to move the lock with your thumb, but the LAWKS disc will stop it from going all the way. In the event that you do disengage the lock while using the knife, it will only make contact with the metal disc which will stop the blade from folding up on you. Incidentally, the Gerber Covert Applegate has the same safety feature as well and it works the same.

You'll find that the liner may disengage, bounce to the LAWKs, and then reengages back to where it's suppose to be. I've spine whacked my CRKT C/K and it has a distinct sound where the LAWKs disc actually hits the liner and it makes a sound.

Good day all,

I have a CRKT Ryan 7 with LAWKS. It is common for the liner to move slightly off the blade, but it will be stopped by the LAWKS disc. This is a very good safety feature preventing the blade from closing in on you in an emergency. That's what the LAWKS is supposed to do. Remember that it is still a folder and you have to live with some compromises vs a fixed blade.

Enjoy your knife, it was a very good purchase and I am sure you will have many cuts on your fingers from playing with it...hehehehehe....just like happened to me!!!!!

Welcome to the Forums!

My experience has been similar to the others, above. The LAWKS works just fine, even though you will be able to detect a bit of movement. It will hold, though, if the going gets tough.

Good luck with the Pro KFF.

My first non-slipjoint was CRKT Point Guard, and I had both the liner and LAWKS fail. While stabbing a bag of magazines, the knife cut into it as deep as it cut into my finger after collapsing, on the very first hit. Now I have a permanent mark on my finger and treat all linerlocks as slipjoints

snap...

no scar for me i was lucky i have the small version so the unsharpened bit at the bottom of the blade hit my finger and nipped me rather that cutting but it still folded on me when i stabbed a door, that was a few hours after it folded on me sharpening a small bit of wood...

I now take great care when buying a linerlock as to the exact designand placing of the lock so it cant catch on my fingers and undo as easily

andr: did you actually manage to crush the LAWKs disk? or did the liner actually squeezed by even though the LAWKs is in place?

Handle gave up upon impact. I think, the liner somehow bends and slides under extreme force applied by the blade. Take the force with is applyed to blade tip, and multiply it by 2*blade length/blade width, because the blade, pivot screw and liner together make a lever.

Now blade is pushed between liner and frame like a chisel into a crack, but with 10 times the force. No wonder the frame couldn't stop it.

So, answering your question, liner squeezed because the frame has "expanded".

Later, I tried to simulate that situation, and found that I have to tighten pivot screw almost so one-hander beacomes two-hander. I swear, I didn't unscrew pivot for easier flicking! But doing so weakenes the lock a lot more.

Then I visited Toronto CKG show and found that no custom maker uses same thin, weak, and easily bent liners as CRKT and at least some other manufacturers do.
