I've designed a lock and would like feedback (no prototype just drawing)

It's had some some up and down play now for a while though.

That's what I was talking about earlier. The achilles heel of the arc/axis/piston lock design are the liners. These locks really lock solid to the touch, they are self adjusting so you always have a wiggle free lock up.

The probleem is that forces applied to the lock are sent directly into those (typically 410 or 420 steel liners) the effect is similar to putting a crowbar between a door and it's frame. It doesn't take much to dent the frame.

I used to feel the axis lock was second only to the Tri-Ad lock but I've changed my mind on that after watching the hard use test videos by Vininull on the Adamas and the ZT0550.

I believe an Axis lock might take more gradual pressure but a good sturdy framelock will handle shock better. Shocks to the Axis lock result in a deformation to the liners inducing unfixable vertical play. Granted the blade will still not close on your fingers but that knife is done.

I personally would rather have a broken knife rather than cut off fingers

the Trident doesn't even have any liners except where the lanyard hole is so you can imagine how that is now 😕. Replaced it in my edc with a Recon 1. Maybe adding a big stop pin like Cold Steel would minimize possible play even less

There are some different variants of this type on the market. CS Bushman, SOG Trindent e.g. and some SAKs

How to the "buttons" actuate the lock without being fixed?

If you look at the first picture the rod is thinner close to the back. I imagined a ring around that bit. That ring has fixed buttons attached to it. the rod can rotate freely. The ring can't because the buttons attached to it are placed in a cut-out in the tube.
..hard to explain for me :grumpy:


About the axis lock's weak point being the liners.. I think that's not the lock design's fault but more the execution. They could make the liners thicker or even make the handles from steel and have the handles be the liners.
