Leave it to the experts at Knife Aid to skillfully restore and sharpen your knives or scissors. From the paring knives to cleavers, each knife is sharpened according to its blade material and design. The main sharpening process is done by hand on air-cooled ceramic belts, with different techniques applied if necessary for specific knives, repairs or blade-angle requirements. After a prepaid, insured and trackable ship-safe envelope is delivered to your door, simply fill it with four knives, shears or scissors and mail back to Knife Aid. In about a week, you'll be slicing and dicing again with razor-sharp, just-like-new blades.
