Why is the lockbar cutout on the outside of the Ti instead of the inside?
Per Mick Strider:

"If you think about the geometry of the knife, and the lock in particular, you will notice that the line of the stress caused by the lock interacting with the blade runs in a (mostly straight) line from the back of the blade down the lock and into the ti side handle.

If the cut was on the inside, the stress would run down the lock bar until it reached the cut, then it would transfer over to the other side of the lockbar…and cause the bar to flex and pop off the blade, rather than transfer the energy down into the rest of the handle."
