Have you ever accidentally overextended a lockbar?

well Rick hinderer says this "I pushed the lock bar way to hard thereby springing it, and of course the blade could no longer lock"

I don't know if I could press a lock bar that hard with my thumb, even on purpose to disable and completely spring the lockbar. I would have to guess, but knowing how much force it takes to set the lockbar in the first place, you would have to put at least 75 pounds of pressure with your thumb, and you would have to hold it there for a little while.

Honestly I think it might break before you could push it out far and hard enough. I can push my Large sebenzas lockbar's inside edge completely past the outer edge of the handle, with about 50 lbs of pressure, and it does not affect it in the least. Keep in mind I cannot do that with my thumb alone, I have to use two hands, one to hold the knife and one to pull on it.
 


It locks back exactly where it always has. not one bit less, and still solid as ever






Now you really think you could push it out that far with your thumb? No way. In order to push it out that far with just your thumb accidentally, you would have to have a hell of a tight grip on it. Therefore Your pinky, ring and middle finger would be wrapped tight around the bottom of the lockbar preventing such force. You would be working against yourself. I call BS on rick's story that he bent the lockbar so far out it wouldn't spring back into place. I could be wrong, but I really don't see it happening, if he closed it one handed. Two handed would be a different story though.

Wow. So not only is it really unlikely that you'll overextend a lockbar accidentally, it's also quite difficult to overextend a lockbar intentionally.
 
wow... good pictures dude, what knife is that?

and no, I've never overextended any of my framelocks, but a decent handful of them do have some kind of lockstop/overtravel "device"

That is a Large Sebenza actually. Given the fact that it is an extremely well made knife, and it is all titanium, you could possibly over extend a steel framelock. But hell, who buys steel framelocks anymore?

Also, I did not just yank on it, and then pry it up with another knife. I did a little at a time checking to see if it would mess it up. little by little I got to that point.
 
I use to worry about that before I got good Ti frame locks, now I don't. The framelocks I have are so solid and like egally08 said would be improbable if not damn near impossible for me to do it accidentally or maybe on purpose.
 
Thanks for conducting that experiment, egally08. It took some guts to do that on a Sebenza. :eek: I'd say you proved the point that lockbar stabilizers exist primarily to protect manufacturers and provide little if any benefit to users. Well done, sir! :thumbup:

This topic popped up when the first ones were seen, ten years ago. The general consensus then agreed that a heavy duty folder DID need the stabilizer, and the buying market followed suit.

It can happen, it's much easier with liner locks, it's not impossible with frame locks. The only ones who see it are using their knife hard, and now hard use knives include the stabilizer to prevent it. The new Kershaw Thermite steel framelock by Hinderer uses it, too.

It's not all about CRK.

Really? How is that possible? I thought the inside of the handle prevented the lockbar in a linerlock from overextending. :confused:

Hmmmm. So I guess the Sebenza isn't a heavy duty folder, huh?

My questions are whether lockbar overextension was really that big a problem 10 years ago and why it doesn't seem to be a problem today on framelocks that don't incorporate stabilizers. :confused:

You know, now that I think about it, I did have the lock bar extend right through the handle scale of my medium size sebenza, The ones that were liner locks.

Hopefully you didn't mean what you said, and you made a mistake. Or you don't know what a LBS is. Either way, :thumbup:
 
edit- ah, nevermind.


edit- you've already qouted me, so yes I would like to see that pic. Thanks.

If you have medium liner lock Sebenza I would love to see a picture of it:p

Ill get a picture up in a minute, its made my Chris Reeves China division. Like I said though, I used it so hard the lock bar went right through the scale!

A linerlock will hit the scale, and can't over extend.
Hard use has nothing to do with it. The only purpose it serves is preventing people from bending the lock back on purpose. Some have done this trying to reduce the pressure it puts the blade thinking it will help the knife open with more ease.

Thanks again, Ken. :) (PS: Sorry. In before the edit. No harm done, though. Some folks need some reminding.)
