Both of my US KBs had a small lip on the underside of the handle, no problem for grinds, a minor issue for cleans but was certainly noticable , tended to catch on my calouses during snatches- would be a major problem for GS snatching. So I removed the coating which took care of the lip/ bump on the nadle, need some more work to egt them totally smooth, will workout with them tomorrow and see how they feel.
