1. A cutting device, said 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 having a slot, 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 there between, said first end configured to pick up a material work piece to be cut over said top side when said cutting device is driven forward; two wheels, said two wheels rotatably mounted on one or more axles positioned respectively on each side of said substantially triangular portion of said body, wherein said two wheels exert a downward force along a first axis on said material coming beneath said two wheels on either side of said wedge member and said downward force produces a tensile stress along a second axis perpendicular to said first axis on said material picked up by said wedge member; 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 said cutting edge intersects a plane of said first axis-second axis; wherein said material gets cut when said material comes in contact with said cutting edge over said wedge member as said cutting device is driven forward. |
