Can anything be done once a frame lock reaches the opposite scale ?
I imagine after reaching the opposite scale it will eventually lead to a certain amount of rock lock. When I got my Spyderco K2 it was around 50-60% lockup and over the years of fair to hard use it’s now at 100% and I can only assume it will eventually hit the other scale and continue to ware developing some rock becoming unacceptable at some point.

The best option is to machine the frame locking so that it can be adapted to it lockbar insert.
1200x680
 
I always wondered how people measure the %.

Is it measured by the center line of the lock? Or is it measured by the side of the lock to the edge of the blade?

If measured by centerline. That's 50%. Directly in the middle and it's fine. It'll take quite a while until it reaches 70%. The lock slides across a ramp on the blade. So it's a combination of wear on both surfaces.

It appears the lock has finally broke in and is seated. The best lock up it ever had.
 
The K2 is already carbidized, and doesn’t have a lockbar insert.

OP: the only thing you can do is machine a slightly fatter stop pin.
 
Not by Spyderco but I believe a fresh layer of carbide can be added.

It’s always been my understanding that it is the percent of contact of lockbar to the blade.

When I bought the knife it was 50-60% and I’ve watched it over the years to the point where it is now and I expect it to continue.
 
With the knife closed. Loosen all the screws and push up on the lock side and down on the show side.Hold and tighten everything up. Should give you a bit earlier lockup.

What is the lock/frame material? Is it titanium?

Thanks I’ll give that a try next time I break it down for a cleaning which is long over due.

Yes, frame & lock are titanium the blade is 10V.

They say titanium but is this solid titanium or just steel coated with a layer of titanium or is it some sort of Ti alloy?
If you got so much wear in one year those scales (and lock) are soft as a butter.
If the lock is soft perhaps you could use plastic deformation to extend it a bit and get back the lock percentage.

Titanium isn't hard at all, no matter the alloy.

But yes, this is what I would suggest. Peening the lock contact area of the frame so it stretches (lengthens) will be the easiest, quickest and best fix. I've done it numerous times.
