For clarification, the first pic above is also the current XHP/CF construction. The pic you posted (my pic) is exclusive to the new FRN/"LW" version. As you said, the pin placement is different but both are doing the same thing.
I think that would infringe on Andrew Demko's patent. Sal and Eric won't even use an Axis type lock, even though that patent has expired. I think we're more likely to see further development of the Powerlock rather than something that mimics the Tri-Ad lock.

The Triad lock works by having a stop pin set in the liners/handle of the knife, and acts as a point where the forces trying to close the blade are directed from the blade tang, to the lock bar "hook", to the stop pin, and from there the handle.ugaarguy wrote: ↑Wed Oct 31, 2018 7:33 amI think that would infringe on Andrew Demko's patent.

I'm aware of the difference. The post I quoted referred to a Cold Steel folder with the Tri-Ad lock, and suggested using that stop pin format, not using the Chaparral style stop pin. Perhaps you should read things in their context rather than getting defensive and telling me I'm wrong.kvdo wrote: ↑Wed Oct 31, 2018 8:29 amThe Triad lock works by having a stop pin set in the liners/handle of the knife, and acts as a point where the forces trying to close the blade are directed from the blade tang, to the lock bar "hook", to the stop pin, and from there the handle.ugaarguy wrote: ↑Wed Oct 31, 2018 7:33 amI think that would infringe on Andrew Demko's patent.

A traditional back lock transfers force from the blade tang, into the lock bar, to the lockbar's pivot, into the handle.
A stop pin mounted on the blade itself (Chaparral) can't act as a means to transfer the force of closing from the blade to the handle as a means of locking. In no way does this infringe upon the Triad lock - that's why it exists on the Chaparral already with no legal issues. I believe Vivi is just asking here for the edge grind to go further down the blade, losing the finger choil.
Why are you asking why?
