Perfect for producing a polished bevel and fine cutting edge on Carbon steel tools. Perhaps our most popular range of belts this robust material is designed to handle the demands of all steels. Not strictly ‘grit sizes' these belts are built using brick and pyramid abrasive shaping. The highest 3000 ‘grit' size will sharpen to two microns (the same sharpness as a disposable razor blade) and provide a factory finish on all steels.
