This handy tool can be used to remove surface rust, tarnish and burrs from parts like the hook assembly, bobbin case, tension discs, thread guides, etc. This rubber honing stick will allow you to quickly and conveniently smooth out and polish any rough spots that would hinder the thread path. Simply take the stick and firmly rub back and forth on the rust or rough spots that need to be smoothed down.

The Rubber Honing Stick is made with an abrasive material, and while good for polishing areas on mechanical parts, it is not recommended for use on any polished chrome or nickel parts such as decorative access plates, slide plates, etc. Measures 2" long, 1/4" wide
