the "neat tricks" i use, are a clear plastic laminate, that you's use to say laminate a fishing license. it's nice and thin, and slides under the lever, preventing that scratch.Don’t know if it’s still the case but the early Ronins had a very stiff takedown lever plunger and it was very easy to put an idiot scratch in the frame. I filed a notch into my lever and it was easy after that.
