A knife sharpener is provided with carbide cutters (25) carried on a sharpening device (11) which can be releasably latched against the action of a spring in an inoperative position. This reduces wear on the blade edge (38) by ensuring that the edge is sharpened only when required. In addition, a blade retaining device (12) is provided which retains a blade (39) in the sharpener even when the carbide cutters are rendered inoperative. |
