Spyderco Gauntlet Select Sharpening System Black/White. Its injection-molded high-impact-plastic base has an integral handguard and specially designed holes that hold abrasive rods at the perfect 40-degree angle (20 degrees per side) to create keen long-wearing edges. The star-shaped holes allow the rods to be turned to expose fresh abrasive surfaces or to orient the edges of the rods for sharpening serrated edges. Ideal for most sharpening needs the Gauntlet Select includes a pair of fine ceramic rods. For very dull knives or to reprofile badly worn edges CBN rods are also available separately.
