The Sparx Deburring Block set offers you a good sturdy grip to safely deburr your freshly sharpened edges. This custom set includes two custom Sparx deburring blocks - one Sparx block with a replaceable abrasive pad for regular steel and one Sparx block with a replaceable leather strop for coated or black steel. Each abrasive pad and leather strop are firmly secured onto the custom Sparx block with industrial-strength hook and loop fastener backing, making them easily removable when it's time to replace them.
