Framelock Engineering Question

[Alpha3]

The cutout along the spine of a framelock obviously creates some sort of inward pressure that causes the frame to move inward and lock the blade. Can anyone explain why this works? Why does a cutout cause the frame to want to move inward? Does the knife maker push that section of the frame into the blade so that is the natural position it wants to return to?

They cut it out so that it can be bent. That's the bending point. And then they bend it to specific tolerances so that it holds that bend and always wants to return to the opposite scale side.

If they left that section at full thickness, it’d probably be very difficult to flex the lockbar over with the strength of your thumb.

Get stronger thumbs, stringbean. Do you even thumbpress?

The lockbar is bent at the relief point to the opposite liner/scale to preload the lockbar to act as a spring.
