No matter what you are cutting, keeping knife edges sharp is essential. No matter how skilled you are with a knife, all sharp edges will dull. The COZZINIPRIMEdge Ergo Steel II is a fast and easy way to straighten and restore knife edges for razor-sharp performance. The ErgoSteel II is an edge maintenance tool used on the production floor. Throughout the day, as a knife edge dulls, the operator can slide the blade through the unique spring-tensioned rods of the Ergo Steel and sharpen the edge in a matter of seconds. The Ergo Steel II consists of a pair of pivoting hardened stainless steel, tempered rods on a food grade, molded polypropylene base. Under each pivoting rod, fully enclosed spring mechanisms provide perfect sharpened angle and tension between the knife edge and stainless steel rods. Both sides of the edge are straightened simultaneously, assuring a perfect edge in seconds. Requires no special training to use, the Ergo Steel II can be mounted on a table top beside each worker, or can be hand-held with the optional handle for left or right handed operation.
