Spyderco Ultra Fine Benchstone with Pouch, 3 X 8 -Inch

Description

Spyderco’s 3 -Inch X 8 -Inch X 1/4 -Inch  ultra-fine ceramic benchstone is flat, thin and ultra smooth for the professional finishing and sharpening of wide tools like chisels, large blades, wood-working equipment, plane irons, and even ski and snowboard edges. Made from Alumina Ceramic, it is manufactured in the United States using a process where a binding agent is combined with Alumina particles that are actually synthetic sapphires. The stone is shaped then kiln fired to temperature of 3000 degrees F (1649°C). Alumina ceramic stones measure 9 on the Mohs hardness scale (out of 10) and don’t require lubricants like oil or water for use. The ultra-fine grit stone tightens and smoothes the cutting edge’s scratch pattern for a keen, hair-popping edge. The stone is thin and light enough for hand-held use when sharpening targe tools. For tabletop sharpening, use its suede carrying case as a base for slip-free use. To clean the stone, wash it in fresh water and scrub with a powdered abrasive cleaner and a scouring pad. Rinse and air dry. 3 -Inch X 8 -Inch X 5/16 -Inch (76.2mm X 203.3mm X 8mm).
