Abstract
A hand operated cutting tool for cutting building materials, such as trim pieces, at an angle. The hand operated cutting tool includes a base, a blade holder with a blade, a handle with a cam rotatably connected to the base, and a working table for aligning the material to be cut with the blade. The hand operated cutting tool moves the blade between an open position and a closed position by rotating the handle.
Claims17
A cutting tool comprising:
- a base including a lower portion and a riser, the riser extending from the lower portion to form a gap between a distal end of the riser and the lower portion;
- a blade holder including a free end and an opposite anchored end, the anchored end rotatably connected to the base;
- a blade connected to the blade holder and positioned within the gap;
- a handle including a cam end with a cam and an opposite grip end, the cam end rotatably connected to the riser at the distal end with the cam in contact with the blade holder, the handle movable from an open position to a closed position;
- wherein in the open position a small radius of the cam contacts the blade holder and in the closed position a larger radius of the cam contacts the blade holder.

A cutting tool comprising:
- a base including a lower portion and a riser, the riser extending from the lower portion to form a gap between a distal end of the riser and the lower portion;
- a working table connected to the base and positioned adjacent to the gap;
- a blade holder including a free end and an opposite anchored end, the anchored end rotatably connected to the base with an axle;
- a blade connected to the blade holder and positioned within the gap;
- a handle including a cam end with a cam, the cam end rotatably connected to the riser with a handle axle and the cam in contact with the blade holder, the handle movable from an open position to a closed position;
- wherein the cam includes an cam profile that gradually increases in distance from a center of the handle axle to an edge of the cam from a narrow distance to a wide distance.

A cutting tool comprising:
- a base comprising a first base half, a second blade half and a spacer positioned between the first base half and the second blade half, wherein the first base half and the second base half each comprise a lower portion and a riser, the riser extending from the lower portion to form a gap between a distal end of the riser and the lower portion;
- a working table connected to the base and positioned adjacent to the gap;
- a blade holder including a free end and an opposite anchored end, the blade holder positioned between the first base half and the second blade half with the anchored end rotatably connected to at least one of the first base half and the second base half;
- a blade connected to the blade holder;
- a handle including a cam end with a cam and an opposite grip end, the cam end positioned between the first base half and the second base half and rotatably connected to at least one of the risers and the cam is in contact with the blade holder;
- wherein the handle pivots from an open position to a closed position, in the open position a small radius of the cam contacts the blade holder and in the closed position a larger radius of the cam contacts the blade holder.
