Check Nick Shabbazz Broken Skull disassembly video.
If Spyderco does that it’s going to enhance the current line big time.
ETA: I just remembered you have Voyager. I think it also has one.
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.
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.
