Abstract
A scoring device which produces a plurality of cuts with a single pass comprises a handle and a body portion containing a movable blade holding assembly consisting of a series of razor blades mounted on a shaft with spacer elements between them. By loosening a thumb screw on the shaft the assembly can be released from a retracted noncutting position and slid out from the body portion to expose a greater amount of the blade edge which will produce a deeper cut. The assembly is then locked at the desired extended position with the thumb screw. The blades can be easily and economically replaced to maintain a sharp cutting edge and the device can be used to score fish.
Claims8
A razor blade holding device adapted for holding a plurality of parallel spaced, replaceable single edge razor blades, said device being adjustable for positioning and locking the cutting edges of the blades at various cutting depths when used for scoring fish and for safely retracting the blades to a position where no blade cutting edges are exposed when not in use comprising:
- a blade holding body having a planar, flat bottom surface and two upwardly extending spaced parallel side walls defining a front and back opening;
- a handle attached to said blade holding body;
- an elongated slot in each of said side walls having a longitudinal axis in a direction parallel to the plane of the planar, flat bottom;
- a plurality of single edge razor blades each having a bottom blade cutting edge and a U-shaped safety backing plate providing an edge on each side of the blade adjacent the blade edge opposite the cutting edge;
- blade securing means to secure (a) said plurality of single edge razor blades in a parallel, spaced apart relation between the two parallel side walls of the body and to maintain the blade cutting edges in approximately the same plane from the planar, flat bottom surface, said blade securing means comprising a blade support member extending between the elongated slots in both side walls with a slot extending element extending out through the slot in each side wall and a plurality of spacer elements slidably mounted on said support member between said side walls, said spacer elements being positioned between the razor blades and under the edge of the U-shaped safety backing plate of each blade with said spacer elements extending further down from the shaft toward the bottom surface than the blades and with said spacer elements abutting the flat bottom surface so as to prevent rotation of the blades about the shaft;
- and
- blade position locking means adjustably locking and unlocking the extending elements against the outer sides of the side walls whereby the blade support member can be positioned toward the front opening and locked in position so the razor blades will extend out past the planar, flat bottom surface for cutting and whereby the blade support member can be positioned toward the back opening and locked in this back position so the razor blades will be maintained back within the parallel side walls where the cutting edges of the blades are not available for cutting.
