If ever there was a sharpener that could do it all, the Redi-Edge® Tactical Pro Knife Sharpener 40 is it. Sharpening, honing, and polishing all in one. Our Duromite™ cutters are harder than any cutlery steel, which means you will get the perfect edge every time. Our Ceramitized coating will protect your sharpener no matter where your adventures take you. You can even sharpen your hooks and needles on the convenient V-groove located on the bottom of The Redi-Edge® Tactical Pro. The Duromite™ sharpening elements are factory pre-set to sharpen most knife blades at a 40° inclusive angle to maintain a 20° double cutting edge. If you hold your knife in your right hand while cutting, order a right handed sharpener. If you hold your knife in your left hand while cutting, order a left handed sharpener.
