Objectively speaking, this is not close to shark lock at all.
For Atlas lock, the motion of the lock bar is linear back and forth, so to unlock, you pull BACK. The lock contact/load bearing points are on the front and middle stop pin.
For Shark lock, the motion of the lock bar is linear THEN curved at the end, so to unlock, you pull BACK AND UP, so that the lock bar clears the tang before the blade can close. The lock contact/load bearing points are on the middle stop pin ONLY. The front stop pin doesn’t bear the load from the lock.
Based in the mechanics, all else being equal(same thickness, same liners, sane materials), I think the Atlas lock is stronger on the static load i.e. weight hang test, since the loads are spread between 2 stop pins and they both need to shear off the handle to fail. However when it comes to impact test, i think the Shark lock is stronger due to the geometry of the lock travel, the fact that it has to be lifted before the blade can disengage. I think it’s easier for the Atlas lock to slip on impact because the lock just need to travel a straight path back for the blade to disengage.
IMO this is more similar to the Snecx’s superlock, with an additional stop pin added in the middle to spread the load. I think this will outperform Snecx Superlock design in every way.
