Abstract: A blade sharpener is disclosed that has a sharpening unit rotatably mounted in a support with an upper portion thereof exposed to enable a knife blade to be reciprocated with a beveled edge maintained in contact with a side of the abrasive wheel of the unit by the engagement of the opposite side of the blade with a blade support, which is part of the unit, the unit turning during such reciprocation. The connection between the unit and the support permits the unit to wobble as it rotates as required by the reciprocated blade. The sharpener also includes a guide rotatable between a position under the unit to a position in which it overlies it and is provided with a slot enabling a scissors blade to be inserted therein with its beveled edge in tangential engagement with the periphery of the abrasive wheel. The guard includes a portion that may be depressed into engagement with the unit to hold it against turning as the scissors blade is reciprocated.
