Abstract

A knife sharpening bar includes a handle that carries a support bar. A flexible tube is tightly fit over the support bar. A hollow ceramic bar is then fit over the flexible tube with an inside surface of the ceramic bar tightly engaging the flexible tube so that the flexible tube provides a cushioning support between the support bar and the ceramic bar, which protects the ceramic bar from directly bearing any external impact applied to the knife sharpening bar. An internally-threaded cap engages an externally-threaded free end of the support bar and abuts against the ceramic bar to thereby secure the ceramic bar in position on the support bar. Collars or other buffering members can be positioned at opposite ends of the ceramic bar.
