How to fix lock failing...

[Txcwboy]

I've never had a folder I made not pass the "whack the blade spline" test, testing the lock. I'm not sure how your supposed to fix it. Bend lock bar more ?
Thanks !

That problem often comes from the contact point between the lockbar face and blade tang being too high. When I first started making folders I thought that it was best to have the whole face of the lockbar contacting the tang. I learned that having a single point of contact down towards the bottom of the tang gives a tighter lockup and reduces the chance of lock rock. If you have an existing knife that you're struggling with, adding a little extra tension to the lock bar spring can help, but probably won't eliminate it.

The knife locks up tight but when I hit the spline on edge of table, it gives away. How do I take a pic of that ?

Video? However I suspect Brandant Robinson is spot on about what he is telling you!

It could be too much lock contact area, too steep of a blade tang angle, or not enough spring tension on the lock bar. But more than likely, its one of the first two or a combination of both.
