To Yekim:
Your liner lock analysis makes sence but is not quite accurate for a well made liner lock. For a poorly made liner lock yes, a difference in liner angle and bottom of blade angle is what pushes the liner out of engagement. For a well made liner lock there is close to zero side force at all.
When starting the Magna project with Kit Carson I visited his shop and spent two days with him learning how to make liner locks correctly.
The way Kit makes a liner lock is by grinding a 7 degree angle on the bottom of the blade. Bending the liner over creates a 7 degree angle as well. Therefore the bottom of the blade and liner should butt up flush with each other at 90 degree angles. If the angle is much higher than lets say, ten or more degrees or there a difference between the blade and liner angle, the lock will either not engage or fail.
