The Smith's Sharpeners Ceramic Edge Pro Electric Knife Sharpener 50245 is an amazing way to keep all of your knives sharp. This Electric Knife Sharpener from Smith's uses interlocking ceramic sharpening wheels in its electric sharpening slot to produce a true, factory quality (or better) cutting edge on your knife blade. These sharpening wheels deliver fast and precise sharpening of both sides of the knife blade EQUALLY at the same time while removing less metal from the blade than other electric sharpeners. They eliminate the possibility of marring or damage to your blade, reduce the amount of time needed to sharpen your knife, and leave no burr on the cutting edge. The sharpness and quality of the cutting edge produced by these ceramic wheels is better than any diamond-coated wheel sharpener on the market today! The interlocking wheels in the Smith's Ceramic Edge Pro Knife Blade Sharpener were designed to sharpen at a 45 degree angle (22.5° on each side) and to provide a Precision Machined Edge configuration. A Precision Machined Edge configuration offers the perfect combination of edge retention, performance, and sharpness. Other edge configurations are generally strong in just one of these characteristics. The 45-degree combined sharpening angle allows this Smith's Sharpener to be versatile enough to sharpen a wide variety of kitchen knives as well as hunting/fishing knives and everyday pocket knife. Like in all of their electric sharpeners, Smith's continues the practice of combining quick and precise electric sharpening with the versatility of manual sharpening elements. This unique combination provides a broad capability to suit multiple blade types and edge conditions....everything from extremely dull blades to already sharp blades in need of a quick touch up to blades with serrations. The Smith's Ceramic Edge Pro Sharpener features two manual, pull-through sharpening slots for initial edge setting and sharpening serrated edge knives. It will sharpen knives of alloy, carbon, or stainless steel with a flat grind on both sides of the blade and knives with large or small serrations. This includes hunting/fishing knives, kitchen knives, tactical style knives, custom knives, outdoor sport knives, or everyday pocket knives. It is NOT designed for use on ceramic blades, Asian style kitchen knives, or knives with a grind on just one side of the blade. The Smith's Ceramic Edge Pro Electric Knife Sharpener comes with soft grip and non-slip rubber feet while offering a beautiful design that fits in any environment.
