Abstract
A hand tool includes a first handle forming a channel, and a second handle including a cutting member. A linkage is attached in pivotal arrangement to the first handle at the channel and to a cutting blade. The cutting blade is attached in pivotal arrangement to the second handle. The first handle is pivotally attached to the second handle via a fastener. The first handle includes a first portion, and a second portion includes a handle grip. The first portion extends substantially along a first reference axis, and the second portion extends substantially along a second reference axis. The first reference axis and the second reference axis extend at an acute angle relative to one another. The channel extends substantially along the first reference axis at the first portion.
Claims16
A hand tool, the hand tool comprising:
- a first handle forming a channel;
- a second handle comprising a cutting member;
- and
- a cutting blade forming a first opening and a second opening, wherein a linkage is attached, via a first fastener, in pivotal arrangement to the first handle at the channel and to the cutting blade at the second opening, and wherein the cutting blade is attached, via a second fastener, in pivotal arrangement to the second handle at the first opening, wherein the cutting blade and the linkage are pivotally attached via a third fastener, and wherein the first handle is pivotally attached to the second handle via a fourth fastener,
- wherein the first handle forms at the channel a first channel end distal to a second channel end, wherein the first channel end is separated along a first reference axis at the first handle from the second channel end, the first reference axis corresponding to an extension between the fourth fastener and the first fastener at the second channel end, wherein the first handle is attachable to the cutting blade in a first operating mode via the first fastener positioned at the first channel end, and wherein the first handle is attachable to the cutting blade in a second operating mode via the first fastener positioned at the second channel end,
- wherein the first handle comprises a first portion and a second portion, wherein a handle grip is positioned onto the first handle at the second portion, wherein the first portion extends substantially along the first reference axis, and wherein the second portion extends substantially along a second reference axis corresponding to an extension between the first fastener at the second channel end and the handle grip, and wherein the first reference axis and the second reference axis extend at an acute angle relative to one another, and wherein the channel extends straight along the first reference axis at the first portion.
A method for operating a hand tool, the method comprising:
- coupling a linkage in a selectively sliding arrangement via a first fastener at a channel at a first handle;
- pivotally coupling a cutting blade to a second handle via a second fastener at a second handle-cutting blade interface;
- pivotally coupling the linkage to the cutting blade via a third fastener;
- pivotally coupling the first handle to the second handle via a fourth fastener;
- sliding the first fastener to a first channel end at the channel, wherein sliding the first fastener to the first channel end configures the hand tool in a first operating mode, and wherein the channel extends straight along a first reference axis corresponding to an extension between the fourth fastener and the first fastener at a second channel end distal to the first channel end;
- sliding the first fastener to the second channel end at the channel distal to the first channel end, wherein sliding the first fastener to the second channel end configures the hand tool in a second operating mode;
- and
- extending a first portion of the first handle substantially along the first reference axis;
- and
- extending a second portion of the first handle substantially along a second reference axis from the first fastener at the second channel end toward a handle grip at an acute angle relative to the first reference axis.
