The Gauntlet is a simple, easy-to-use sharpening system that enables even novice users to achieve razor-sharp edges in just a few minutes without electricity, oil, water, or complicated clamps or fixtures. 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, including reprofiling badly worn edges and very dull knives, the Gauntlet Premium includes both fast-cutting Cubic Boron Nitride (CBN) rods and fine ceramic rods.
