The plastic tube cutter comprises: a shell-body; a cutting-unit; and a pressing-arm; wherein the cutting-unit having a semicircular concave-arc end-face at one end is pivotally set in the shell-body; wherein four rolling-wheels corresponding to each other are spacedly set on two sides between the concave-arc end-face and the opening, and the other end of the shell-body has a gripping-arm; wherein the pressing-arm is pivotally set at the bottom of the shell-body and spaced apart from the gripping-arm to face with each other; wherein the four rolling-wheels of the semicircular concave-arc end-face are provided for accommodating a plastic tube body. In addition, a hooking-piece and a rod-body are respectively set on opposite sides of the gripping-arm and the pressing-arm to hook the hooking-piece and the rod-body. Therefore, maintaining the cutting freedom and the flat-smooth cutting, and cutting the high-thickness plastic tube body in a rotation way can be achieved.

Shears having two limbs connected at a revolute joint, each limb comprising a handle region at one end and a cutting edge at the other end. One limb is fixed relative to the revolute joint during an opening and closing movement, and one limb is movable. The limbs move between an open position and a closed position while being limited by a stop and, in the closed position, the cutting edges pass each other over substantially their entire length. On the handle side of the revolute joint, one limb extends relative to the other limb such that it is supported in a planar manner on both sides in a region of overlap with the other limb, wherein the limbs comprise surface regions which, in the closed position, rest against one another in the region in which they are on top of each other and are each exposed on the opposite side.

Disclosed herein is a cutting device. The cutting device includes a first subassembly, a second subassembly, and a fastener. The first subassembly has a first blade and a handle. The first blade includes a circular opening. The second subassembly has a second blade and a handle. The second blade includes an elongated opening. The fastener is connected between the circular opening and the elongated opening.

A cutting tool according to some embodiments of the disclosure includes a stationary handle and a movable handle pivotally attached thereto, a blade receiving gear mounted on the stationary handle, a blade removably mounted to the blade receiving gear, and a spring-loaded slide plate mounted to the blade receiving gear for holding the blade in the blade receiving gear. The blade seats within a notch of the blade receiving gear and the slide plate engages with a notch in the blade. The slide plate can be removed without the use of tools from engagement with the blade to allow user to easily remove the blade from the cutting tool.
