<p>A manual knife sharpener (10) is provided with angle control structure. The structure includes a guide member (20) having a guide surface (18) which forms an angle with the abrasive surface (14) of the sharpening member (12). When the blade (16) is inserted into the space between the abrasive surface (14) and the guide surface (18) the blade (16) presses against the guide surface (18) to displace the guide surface (18) linearly in a direction perpendicular to the guide surface (18) so that the movement is a lateral movement in the same plane without any pivoting or twisting of the guide member (20). Thus, the angle between the guide surface (18) and the abrasive surface (14) remains constant regardless of the extent of displacement of the guide member (20). <IMAGE></p> |
