Abstract: A knife handle comprising a handle body with a proximal end and a distal end, a sharpener body removably attached to the handle body, the sharpener body comprising at least one cut-away for housing a replaceable sharpener, the sharpener body rotatable relative to the handle body, and a selectively actuatable locking mechanism for locking the sharpener body in place on the handle body. The selectively actuatable locking mechanism may have a first, locked position wherein the sharpener body cannot rotate relative to the handle body and a second, open position wherein the sharpener body can rotate relative to the handle body. The selectively actuatable locking mechanism may be biased in the first, locked position.
