liner lock and a lock back.

[SanitySource]

I was wondering and i came up with the idea of a knife with a liner lock and a lock back.

I dont see why it cant be done. it wouldnt be too practical, but im sure if someone made it, it would sell.

Let me know what you think,

 

[johnnycakes8787]

i dont think its necessary to have that much security of a blade! it would be too heavy and bulky in my opinion!

 

[John Frederick]

It would be to difficult to close.

 

[SanitySource]

i know its unpractical, but its just an idea. so maybe you could choose to only deploy one or both if you know your gunna be fighting.

 

[orthogonal1]

Why do you think it would sell? What is the advantage of the combination?

Liner-locks are not the most reliable nor strongest locks out there and lock-backs are often difficult to close one handed.

It would be to difficult to close.

no, you just use one hand to push down the backlock, another hand to release the liner, and your third hand to close the blade.

It could be a back lock more similar to a spyderco, in that it would be about halfway down the handle. Using one hand with the blade facing up use your middle finger to disengage the back lock and your thumb to undo the liner. Use your free hand to close the blade.

It's nearly the same as closing a CRKT with the auto-lawks system. Depending on the way it was implemented it could possibly still be closed one-handed with practice.

I was thinking and I came up with the idea of the "quad-lock".

It has a compression lock, liner lock, lockback and slipjoint all in the one package.

 

[go mike]

I thought of a locking system that involves so many locking methods, it would be called a fixed blade.

Liner locks suck.

It would also be a learning curve to close it. I would say it certainly would be difficult if not impossible to close one handed. The tang design of a lockback doesn't leave much metal to make a very large contact for a contact of a liner lock. You would need to cut into what would normally be the rest to keep the blade from bottoming out when closed where the edge comes into contact with the spring if the rocker arm does not stop it at the right time. The back spring generally speaking needs that area on the blade you'd create the liner lock contact and it needs it to put the downward pressure on the blade which keeps the tip down in the body in the closed position and also prevents the folder from flicking open or falling into the gravity knife illegal category. Since that metal would not be there because of the contact interface created for the liner lock you'd probably have to put an active detent ball to keep the tip down since the back springs normal action there would be inhibited I think.

thankyou STR, yeah i wanted to know if it was possible.

Wow that was way better than my explanation....nice work sir

However, it would be even slightly more nonsensical and unnecessary than the lawks.

Auto-lawks...Talk about your all-time dumb marketing gimmicks...

 

[enderwiggin]

Really not seeing the point. There are much more secure, more simple ways of doubling up a lock, like adding a screw-in pin that locks the blade open, or a bar that slides into a slot in the blade.

You'd be combining two contradictory closing methods. To one-hand close a lockback, you have to depress the lock, and shake or tap the blade downward to free it so it can be closed. With a linerlock, you want to keep the blade fully open, and slide the liner out of the way.
