• Fine grits include silicon carbide and pyramid alumina for smooth finishing and luster
• A soft yet strong blended fabric backing with a flat, smooth joint reduces edge jumps and promotes safe, controlled grinding
• The dual-directional tape design helps maintain belt orientation and consistent contact with the sharpening surface

How this kit fits into your workflow
