Abstract

A hand driven cutting device having a substantially pistol shaped body assembly, a knife blade clamped between a first substantially pistol shaped body part and a second substantially pistol shaped body part of the substantially pistol shaped body assembly, a pair of wheels with each wheel attached to the lower periphery of each front end portion via an axle and lifting and supporting element extending from the rear of the front end portion. The cutting action of a material work piece is facilitated by a stress induced on the material work piece at the point of contact between the material work piece and the cutting edge of the knife blade due to stretching of work piece against clamping pressure exerted by the pair of wheels on the material work piece when the cutting device is pushed forward by a user.

Dependent claims

A cutting device comprising a body, said body comprising two opposing sides, said opposing sides being mirror images and each having a front end fastener hole, a rearward fastener hole, and a supporting fastener hole, said two opposing sides being connected together by a front end fastener disposed in said front end fastener holes, a rearward fastener disposed in said rearward fastener holes, and a supporting fastener disposed in said supporting fastener holes to form said body, said body having a forward facing substantially triangular portion and a rearward facing substantially rectangular portion, said front end fastener and said supporting fastener are located in said substantially triangular portion, said rearward fastener located in said substantially rectangular portion;

a wedge member, said wedge member comprising a top side, a bottom side, a first end, a second end thicker than said first end, and a supporting element, said supporting element projecting upwards from said top side of said second end of said wedge member, said supporting element positioned in-between said opposing sides of said body in said substantially triangular portion, said supporting element has a central recess to receive said supporting fastener, said top side of said wedge extending along a bottom surface of said substantially triangular portion of said body to define a space therebetween;
an interior cavity defined by said opposing sides of said body and extending through said bottom surface of said substantially triangular portion;
a blade with a forward cutting edge and a rear dull edge, said blade being received in said cavity wherein a portion of said cutting edge extends outward from said bottom surface of said substantially triangular portion of said body and into said space so that said portion of said cutting edge is exposed;
and two wheels rotatably mounted respectively on each side of said substantially triangular portion of said body.

1 more element

A device for cutting lamina comprising:

an elongate housing, said housing comprised of two opposing sides, each of said opposing sides being mirror images and having three apertures, said opposing sides connected together by disposing three fasteners respectively through each of said three apertures, said housing having a front substantially triangular portion and a rear substantially rectangular handle portion;
a wedge member, said wedge member having a top side, a bottom side, a front first end, a rear second end thicker than said first end, and a vertical fin, said vertical fin located on said top side of said rear second end, said vertical fin having a central recess to receive one of said three fasteners to position said fin between said two opposing sides of said housing in said substantially triangular portion in such a way that a space is defined between said top side of said wedge member and a lower surface of said substantially triangular portion;
an interior cavity defined by said opposing sides of said housing and extending through said bottom surface of said substantially triangular portion;
a blade with a forward cutting edge and a rear dull edge, said blade being received in said cavity wherein a portion of said cutting edge extends outward from said bottom edge of said substantially triangular portion of said body and into said space so that said portion of said cutting edge is exposed;
and two wheels rotatable supported respectively on opposing sides of said substantially triangular portion.
