<p>An abrading device (10) comprising a housing (12) to provide a reservoir (14) for cooling fluid, an abrading wheel (15) mounted in the housing (12) for rotation about a substantially horizontal axis, first means (18) to direct cooling fluid from the reservoir (14) upwards upon rotation of the abrading wheel (15) about its axis, and second means (20) to direct the said upwardly directed fluid across a sharpening face (25) of the abrading wheel (15) to effect cooling of an edge tool being sharpened against said face (25). An implement holder is mounted for movement relative to a surface portion (25) of the abrading wheel that is directed at a small angle, e.g. less than 5° (preferably about 1°), to the perpendicular to the wheel axis and is in use in contact with the implement.</p> |
