AccuSharp Electric Knife Sharpener Cordless Features The AccuSharp Electric Knife Sharpener Cordless uses a diamond coated sharpening disc rated at 800 grit preset at a 21 degree angle to quickly restore a true edge on dull or damaged blades. That preset angle takes the guesswork out of sharpening so even a first-time user gets consistent repeatable results on knives of varying steel types. The motor drives this coarse disc at up to roughly 6334 RPM under load removing metal efficiently to reshape a rolled or chipped edge before moving to finer refinement. Three total sharpening slots route the blade through a complete progression from coarse grinding to fine polishing in a single pass. Following the diamond disc stage ceramic finishing rods rated at 1500 grit and preset at the same 21 degree angle polish the edge to a smooth hair-splitting finish. This two-stage approach mirrors the progression used by professional sharpening services giving a finished edge that is both sharp and durable rather than simply thin. The cordless lithium battery design means the unit works anywhere from a kitchen counter to a hunting camp far from an outlet and recharges fully over USB between uses. At just 0.8 lbs the AccuSharp Electric Knife Sharpener Cordless is light enough to pack along and dependable enough to keep kitchen knives hunting blades and everyday carry knives performing at their best.
