A knife sharpener of the kind having a hollow scabbard or housing for a knife blade, and a blade sharpening device arranged to be engaged by the blade cutting edge as the blade is moved into and out of the housing. The sharpening device is mounted on the front end of a carrier member which has its rear end pivotally connected to the housing so that the front end can be swung towards and away from a top wall of the housing. A biasing spring urges the front end of the carrier towards the housing top wall. A reaction member is disposed between that housing top wall and the carrier member and is pivotally connected to the housing for movement about an axis which is parallel to the carrier pivot axis and is located between the ends of the reaction member. A rear end of the reaction member engages an upper surface of the carrier member at a location between the carrier pivot and the zone at which the biasing spring acts on the carrier member. The front ends of the carrier and reaction members are separated when a knife blade is inserted into the housing, but the engagement at their rear ends is maintained at all times. |
