Sog has some new version of it as well believe they’re calling it sr lock or something

SOG is calling theirs the XR lock.

IIRC, the patent for the Axis lock ran out but the copyright for the name "Axis lock" is still valid so companies are just coming up with a new name for their version. That is why SOG, Gerber, etc aren't using the name "Axis lock". If I'm wrong, someone will correct me.

SOG was already using something very similar to the axis lock, they named it the Arc lock, it was already in production many years before their new XR lock.

The new SOG XR lock actually bears much less resemblance to the benchmade axis lock when compared to their Arc lock.

You can actually see examples of the Arc lock in my profile pic of the SOG tomcat 3.0 and fat cat. These knives were released 3-4 years ago.

The mechanism is virtually identical except that ñńhethe path of the axis lock bar is pulled straight horizontally, but the path of the arc curves upwards

Gerber and one Italian knife manufacturer.
The Italian manufacturer is Lionsteel and their lock called the tactical operation lock or TOL might look like an axis lock but is quite different technically: It doesn't lock the blade like the Benchmade Axis lock and all similar locks. The TOL is a slipjoint where the spring is locked. You won't be able to flick TOL knives open by pulling back the bar and moving the knife because the blade is still held in place by the spring's tension even when the bar is gone. Thus the opening action cannot be as flicky and smooth as axis lock knives can be and also TOL automatics aren't possible. However, the advantage is that you can use it on knives that have to be two hand opening. Lionsteel also has a version where you have to push back the bar in order to open it so it can double as a locking mechanism that keeps the blade in the handle. This was used for a skinning knife and a Pohlforce knife.

Exactly, surprised no one else commented on this. MY CBBL Spydercos are quite different than my axis lock BM's.

I have a BM 530 Mel Pardue and a Spyderco P'Kal, there's a big difference. If I had to choose, it'd be the Spyderco.

All axis locks use Omega springs. I fidget like a maniac, means I open and close folders non stop and I've busted 3 benchmades and 2 SOG arc-locks (they use omega springs)

My Spyderco ball locks (uses helical springs I think it's called) have lasted my use for many many yers, far outlasting the omega springs.

What's TRM?

Cotherian, Doug Ritters rsk uses a beefier omega spring for just that reason. Now that Ritter released the mini rsk I will probably pick one up.

I no longer purchase Benchmades so Im glad to see so many using the axis lock, by far my favorite.

Thanks to all that posted.
