I recently took down one of my small 21's. I wanted to improve how the blade opened. The blade opened fine but I knew it could be even smoother.
I disassembled the knife cleaned the various parts. I used a Norton 4,000 grit water stone to lap each side of the washers. You can see, in the photo, the high and low spots in the washer. I was careful to not over lap the washers. In fact, I did not lap away all the high spots. I also briefly lapped each side on an 8,000 grit stone. I reassembled and tested the knife several times to ensure I did not remove too much material. Once the action was to my liking, I stopped lapping.
Also, I have found that a short piece of molded plastic from a school folder slipped over the edge works perfectly to protect me and the blade.
I am pleased with the improvement in the action of the knife. The blade glides open and it will fall under its own eight when the lock bar is released.
