Knife Aid is the only nationally available mail-in knife sharpening service on the market. Before Knife Aid, the only option was local knife sharpeners (at farmers markets or grocery stores) and retail stores that offer sharpening, but Knife Aid’s techniques are designed to what’s best for your knives and your convenience. Knife Aid’s vision is to offer the fastest, the most convenient and reliable knife sharpening service in America. Knife Aid has been featured on ABC’s hit shows Shark Tank (Oct 20th) and the View (Nov 14th).
