So I made my 2nd and 3rd liner lock knives recently. Got pretty much everything done and fitted up. During the final fit and test, I noticed that both had some lock rock. Meaning I could move the blade slightly in the open/close direction. It isn't much, but enough to not let it be. These aren't for sale, they were gonna be gifts for family members, so I'm wondering if anyone has any ideas on a "fix" short of making a new blade or lock side liner. There isn't much play at all. I have to use some just a little bit of force to get the "play" in the blade. They was only 30-40% lockup when I test fit it during my lock face grinding, so I don't know if something happened during heat treat or what. It is 1084 steel.

I have read that I could peen the lock bar to elongate/flatten it a bit. Which in theory may work.

The solution I am leaning towards is replacing my 1/8" stop pin with a 9/64" stop pin and see if that will change the lock up position enough in the open position to eliminate the lock rock.

What do you guys think?

Make sure the point of contact with lockbar is only on the end of tang. What angle is it ground at?

From what I can see, the lock up is at the bottom corner of the tang like it is supposed to, just somehow I must have overground the lock face, although it was darn near perfect when I was test fitting it.

I ground the lock face around 8.5 degrees.
