The Sparx Deburring Block set gives you a sturdy grip to safely deburr your freshly sharpened steel. 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.
