Why isn't there a user adjustable frame lock?

Hi
Why isn't here a user adjustable frame lock where the end user can (lengthen) the frame lock insert to control lock up and to make up for lock face wear?
 
It's a great idea and the spyderco invention on some of their frame lock militaries have a factory replaceable insert. The problem I see with the idea is two fold. Number one if a company gives people that much responsibility they will screw it up and then the company will be responsible for fixing all the fixings. The second problem is a frame lock is a finicky beast. It is either right or really really wrong. If the end user can not find that sweet spot the knife will have the structure integrity of a peanut butter sandwich. Otherwise I think it is a smart idea.
Thanks

There is.

Lionsteel SR-1 Titanium. This is a pic of the aluminum version, but the Ti is the same.

I don't think the SR-1 is adjustable, but the ZT 0777 also has a steel insert on the Ti frame lock, and you can adjust it so that the lockup is either late or early.

Good question.
Black Bear Knives offers a single locking spring bar that can be replaced instead of replacing the whole liner-lock.
 
a user adjustable framelock is not a good idea IMO, too easy to screw up things
replaceable inserts on the other side, are.

anyways, they should come from the factory well setted and ready for years of use
 
Like mentioned, the new ZT 0777 is supposed to have one. Not sure if I like that though, there's enough moving parts in folder already. Time will tell how that works out.

I agree. Some folks are not competent enough to tweak thing, and that opens p liability issues that can bankrupt any company.

Actually, as long as the geometry is right from the factory (tang bevel matches what is needed for the length of lock bar) then adjusting the lock should have no bearing on integrity, since being at 20% or 90% is effectively the same geometry.

Getting a frame lock right is all about the imaginary circle that the lock bar makes. Longer lock bar, the bigger the diameter of the circle, the less extreme the blade tang angle needs to be. Vice versa for a shorter lock bar. As long as the blade tang is cut to match that "circle" then the lock will be solid, period.


With that said, I don't think people as a whole are competent enough to change the orientation of their pocket clips, much less adjust a lock.
 
Why? All I see are lawsuits.

A good portion of our knife-using community can't even sharpen their knives properly.

Why would any knife company want to have that kind of liability in letting users be able to control the locking mechanism of their knives?
 
Hi
We make cars that go 200mph . Does that make Ferrari liable if someone drives it into a wall?

Heard of liability insurance? You need that before you can legally drive a car on public roads.

Besides, if you take that 200 mph car and then try to personally tweak it, you void your warranty.
 
Aren't there knives that have oval/hex stop pins to accomodate/fix this problem??? It's alot simpler than the lock bar as you just roll the stop pin a bit and lock it in place and voila! New, earlier lock-up as the distance between the blade tang and frame/liner lock is now shorter....

I thought the Benchmade MPR had something like that with the stop pin idea but I'm not sure. :foot:

:D

Lets see some pics of the stop pin for clarity if anybody has one (an MPR that is).

Well, while the 755 does have the end user adjustable stop pin, and it DOES work to adjust the lock up really easily - benchmade doesn't really advertise that feature as being something that the end user can use. I think it's kind of a "hidden" feature that Benchmade threw in to make their life easier at the factory, all the while knowing that people with a little bit of knowledge will know how to adjust it. The people without that knowledge won't know what it is or how it works, so they most likely won't mess with it.

Good point CTS! Maybe we should lock this thread down so folks don't find out about it. :cool:

Only kidding.

I figured out the stop pin trick ages ago on some of my folders; once a flat spot has worn on the pin where the blade hits it from opening the lock bar definitely settles in deeper. I've been able to tune up a few knives by rotating the pin to a fresh spot for it to wear again. :thumbup: Pretty much all my knives are users so I enjoy learning what makes each one work and how they're built etc...
