I did not find how to contact Demko directly, so I decided to write here.

The last few months I have been using a triadlock knife very actively. An excellent strong lock, but has a drawback, like all locks with a sliding tooth. The tip of the tooth wears out in the field. On my Puma Prince and 110s, it was also pretty fast - the tip grinds off and the lock turns into an analogue of a slipjoint.

Wear occurs at the point of contact of the tooth - the tooth is erased and the track along which it rides also begins to deteriorate. As a result, wear progresses at an increasing rate. I marked the wear areas in red:



Triadlock has more metal, but in the absence of cleaning and abrasive fine dust, it also wears out. Last week I received my first sobenza ummuzan. The ceramic ball is just lovely. Chris Reeve is simply a god of folding knives, as is Michael Walker.

I looked at how the lock with a ceramic ball works and realized that if you introduce the same ceramic ball into the tip of a tooth in a triadlock, then it will be almost eternal. Definitely this increases the cost of the knife. If it's good way, then you can use it on some anniversary or special versions that are expected to have a long life. This will not reduce or increase the strength of the lock itself, but will reduce abrasive wear. It turns out a certain analogue of a ball bearing, but not the one that holds the blade from the sides, but keeps the tooth on the track:



Also, the balls can be inserted into small gentlemen's folders, such as those made by Hoel or Lake. I don't think it will affect the price much, lol

Interesting.

I've seen people do dumb stuff with Triad-lock knives, and I would be worried about putting ceramic anywhere in the lock. If you decide to do it, let us know how it works.

Unfortunately, I do not have the skill and press, and also a suitable ceramic ball to properly insert it into the knife. So it's all speculative. In theory, you just need to make a small blind hole, place the ball and press it in a circle, like on Sebenza. If I had the opportunity, I would do this before posting on the forum

To install it in the tooth, it seems that you need to use a press, or some kind of jewelry technique, like compressing precious stones in a setting

When you say using it actively are we talking fidget toy? Quality control machine designed to open and close to destruction? I just can't see a Triad lock design wearing out without something strange happening. It seems like a solution looking for a problem.
 
I've used several lockbacks over the years, Buck, Spyderco, CS Triad, and have yet to notice any significant wear -- albeit I keep them clean and lubed. The blades are more likely to need replacement before the lock mechanism wears enough to make a difference.
 
Theoretically, a ceramic faced frame lock might outlive a lockback, but it would probably take decades of normal use to matter. It's an interesting thought, but may not have any practical value.
 
Not sure if I totally understand what you mean but take a look at the Bestech Tonic kind of sounds like what you are talking about. It has a detent ball in the lockbar that rides along the blade
 
Have used several triad folders at work the last few years. Clean them only occasionally. Haven t noticed any problem with any of the lockups yet.
 
I don't understand??? I carried a Puma Duke daily for about 15 years. There is no appreciable wear on the lock.
 
Have you ever seen or even heard about a Tri-Ad lock wearing out in the way you’re describing? I’ve seen it on lockbacks with shallow lock bar seating, but never even heard of a Tri-Ad getting anywhere close.

There’s a LOT of steel that would have to wear away.
