Abstract
A knife includes a body including a first end, a second end opposite the first end, and a longitudinal axis that extends centrally through the first end and the second end. The knife further includes a first scoring tip that points in a first direction, a second scoring tip that points in a second direction opposite the first direction, and a scoring tip axis that extends centrally through the first scoring tip and the second scoring tip. The scoring tip axis is perpendicular to the longitudinal axis. A chisel extends from the second end of the body and the longitudinal axis of the body extends centrally through the chisel.
Claims20
A scoring knife comprising:
- a handgrip;
- a body having a first end and a second end opposite the first end, the body extends at least partially through the handgrip;
- a first scoring member attached to the body, the first scoring member having a first scoring tip that points in a first direction;
- a second scoring member attached to the body, the second scoring member having a second scoring tip that points in a second direction opposite the first direction;
- a chisel positioned adjacent the first end of the body;
- a longitudinal axis that extends centrally through the body and the chisel;
- a scoring tip axis that extends centrally through the first scoring member and the second scoring member, the scoring tip axis perpendicular to the longitudinal axis;
- and
- a blade hook formed on the body, the blade hook extending at least partially between the first scoring member and the longitudinal axis of the body, the scoring tip axis forms a tangent line of the blade hook.
