Abstract

Sharpening equipment in the form of sharpening device (10) comprises jaw fashion arranged gripping means (12) for gripping an item such as a knife (50) of which the blade requires sharpening, a sharpening means carrier in the form of a sharpening element holding base (14) releasably holding a sharpening stone (16), a guiding layout in the form of a guiding rod (18) mounted to reciprocate along an adjustably mounted support guide (20) in parallel with the sharpening surface (16.1) and an angle adjustment facility as provided by a connecting arm (24). The arm (24) extends integrally with respect to the gripping means (12) and is swivellably connected to the leading end of the rod (18). A disc (26) as mounted about the swivelling position presents a graduated dial providing face (28). The gripping means (12) is arranged to cause its central axis (46) to pass through the pivotal point (48) between the gripping means (12) and the rod (18).
