ABSTRACT:
A knife sharpener including a scabbard for receiving and protecting a knife blade, and a sharpening device mounted on the scabbard for engagement by the blade cutting edge during movement into and out of the scabbard. The sharpening device is supported by a carrier member which is pivotally mounted within the scabbard so that the sharpening device can be moved towards and away from a top wall of the scabbard. A pivoted reaction member is located between the scabbard top wall and the carrier member, and has front and rear reaction zones which are engageable with a knife blade and/or the adjacent surface of the carrier member, at opposite sides respectively of the carrier member pivot. The reaction member pivot is located rearward of both reaction zones and is parallel to the carrier member pivot. A U-shaped biasing spring engages both the carrier member and the reaction member to resist separation of their front end portions.
