Abstract
A cutting tool (100) includes a top blade (102) and a bottom blade (104). The bottom blade (104) is pivotally coupled to the top blade (102). The top blade (102) and the bottom blade (104) together perform a cutting action on an object place between them. A first handle (108) is operatively coupled with the top blade (102). The first handle (108) defines a front portion (109) and a back portion (111). A second handle (110) is operatively coupled with the bottom blade (104). The cutting tool (100) is characterized in that in closed position of the cutting tool (100), at least a part of the second handle (110) at least partially encloses the back portion (111) of the first handle (108).
Claims13
A cutting tool comprising:
- a top blade;
- a bottom blade pivotally coupled to the top blade, wherein the top blade and the bottom blade together perform a cutting action on an object placed therebetween;
- a first handle operatively coupled with the top blade, wherein the first handle comprises a front portion, a back portion and a first inner side;
- and
- a second handle operatively coupled with the bottom blade;
- wherein, in a closed position of the cutting tool, at least a part of the second handle at least partially encloses the back portion of the first handle, and
- wherein the cutting tool further comprises a drive unit and a slider or trigger to activate and deactivate the drive unit,
- wherein the drive unit is configured to selectively provide a supplementary motor force to assist pivoting the top blade relative to the bottom blade,
- wherein the slider or trigger is disposed at the second handle and operable by a user of the cutting tool to power on and power off the drive unit and to selectively provide the supplementary motor force via the drive unit,
- wherein the second handle comprises a recess defined by a second inner side of the second handle,
- wherein the first inner side and the second inner side are both arcuate and the first handle is conformal with the second handle in the closed position, and
- wherein the second handle comprises the recess in which the first handle is arrangeable or arranged in the closed position of the cutting tool, wherein a wall of the second handle forming the recess has a contour of an arc-shaped or curved contour, corresponding to a contour of an arc-shaped or curved contour, of the first handle such that the corresponding contours of first and second handle are arrangeable or arranged closely adjacent to each other in the closed position of the cutting tool.
