I have a salt2 in LC200N
essentially a Delica handle and it has some pretty good lock rock.
Will changing scales and going with a metal backspace fix this?
The knife is brand new so it is not wear related. Love the blade but the lock rock is just plain sloppy.

Re: Rock around the clock
Assuming the lock rock is due to how the lock bar engages the blade tang, I wouldn't expect it to make it better.
