Abstract
A soapstone sharpener for providing a fine marking edge on the stone, the sharpener being comprised of an elongated member having facing legs forming a V-shape in cross section and having abrasive material secured on the inner faces of the legs to form inner abrading surfaces of V-shaped cross section. The soapstone is rubbed on the abrasive material within the V-shaped cross section to form the soapstone so as to be complementary to the V and have a fine marking edge.
Claims6
In a soapstone sharpener for providing a fine marking edge on the stone, said sharpener comprising:
- an elongated member having facing legs forming a V-shaped cross section,
- abrasive material secured on inner faces of the legs forming the V to form inner abrading surfaces of V-shaped cross section,
- said elongated member having extensions on said legs at one end thereof in the elongated direction,
- said extensions being in proximate relationship,
- means associated with said member for attachment to carrying means, and
- clip means being positioned within said extensions and extending over one end of said abrasive material to secure it in place,
- whereby a soapstone may be rubbed on said abrasive material within the V to form the soapstone to be complementary to the V and to have a fine marking edge.
In a soapstone sharpener for providing a fine marking edge on the stone, said sharpener comprising:
- a single elongated member having continuous facing legs joined at their inner ends to form a V-shaped cross section,
- the inner ends of the joined legs forming the pointed end of the V and the outer ends of the legs being spaced and free, and
- abrasive material secured on inner faces of the legs forming the V to form inner abrading surfaces of V-shaped cross section,
- whereby a soapstone may be rubbed on said abrasive material within the V to form the soapstone to be complementary to the V and to have a fine marking edge,
- said elongated member has extensions on said legs at one end thereof in the elongated direction,
- said extensions being in proximate relationship,
- means associated with said member for attachment to carrying means.
In a soapstone sharpener for providing a fine marking edge on the stone, said sharpener comprising:
- a single elongated member having continuous facing legs joined at their inner ends to form a V-shaped cross section,
- the inner ends of the joined legs forming the pointed end of the V and the outer ends of the legs being spaced and free, the inner ends of the legs terminating externally in the point of the V, and
- abrasive material secured on inner faces of the legs forming the V to form inner abrading surfaces of V-shaped cross section,
- whereby a soapstone may be rubbed on said abrasive material within the V to form the soapstone to be complementary to the V and to have a fine marking edge, and
- a pair of spaced spring clips extending transversely to the elongated direction and extending downwardly and outwardly from one of the free ends of one of the legs, each clip being biased toward the outer surface of the leg for attachment on sheet material between the clips and the leg.
In a soapstone sharpener for providing a fine marking edge on the stone, said sharpener comprising:
- a single elongated member having continuous facing legs joined at their inner ends to form a V-shaped cross section,
- the inner ends of the joined legs forming the pointed end of the V and the outer ends of the legs being spaced and free, the inner ends of the legs terminating externally in the point of the V, and
- abrasive material secured on inner faces of the legs forming the V to form inner abrading surfaces of V-shaped cross section,
- whereby a soapstone may be rubbed on said abrasive material within the V to form the soapstone to be complementary to the V and to have a fine marking edge, and
- one of said legs having tabs at its ends extending in the elongated direction,
- said tabs being securable to a member for carrying said sharpener,
- said tabs are connected to said leg by respective bends at the leg ends,
- said bends being away from the plane of the leg and then toward said plane to position said tabs in the plane of said leg.
