A sharpening tool comprising:
- opposing sharpening elements arranged to form a generally “V” shaped sharpening slot;
- first and second elongate guide members extending from opposite sides of said sharpening slot, each comprising a base spur gear element and an elongate eccentric guide pin element;
- wherein a base spur gear element comprises a mounting shaft having a toothed gear at a first end and an elongate eccentric guide pin element at the opposite end, the toothed gear of said first guide member arranged in mating engagement with the toothed gear of said second guide member.
A sharpening tool comprising:
- a mounting block, comprising slots arranged for mounting opposing sharpening elements comprising overlapping rectilinear plates having sharpening edges arranged in a generally “V” shaped sharpening slot arrangement;
- first and second elongate guide members extending from said mounting block on opposite sides of said sharpening slot, each guide member comprising a base spur gear element and an elongate eccentric guide pin element;
- said base spur gear elements comprising a mounting shaft having a toothed gear at a first end and an elongate eccentric guide pin element at the opposite end;
- wherein the toothed gears of said first guide member is arranged in mating engagement with the toothed gear of said second guide member in a hollow of said mounting block.
A quadrilateral plate sharpening element comprising opposing generally parallel sharpening edges and opposing generally parallel angled ends, said ends being angled to said edges so that when sharpening edges of opposing plate sharpening elements are arranged to form a generally “V” shaped sharpening slot, ends of the opposing plates lay at about a 90° angle to a centerline bisecting the “V” shaped sharpening slot.
