A tube cutter includes a main device, a blade and a controller. The main device includes a fixed member and a movable member, wherein the movable member is movably connected to the fixed member, and a cutting space is formed between the fixed member and the movable member. The blade is fixed to the main device, and the blade has a blade portion in the cutting space. The controller, which is provided on the main device, can be operated to move the movable member for changing a size of the cutting space.

Hockey sticks or other tubular shafts have historically been cut using a hack saw with the shaft resting on the lip of a garbage can resulting in slow and inaccurate cuts. A new device for cutting a shaft comprises a holder for receiving the shaft, and an arm rotatably mounted at an end of the holder. The holder includes an internal passage, sized to receive the shaft, which extends outwardly through an opening at the end of the internal passage. A set of jaws are mounted on the rotating arm, each jaw includes a saw blade extending across the opening perpendicular to the shaft. The jaws are spring biased together at a first end for engaging the shaft, whereby relative rotation of the arm and the holder results in the saw blades sawing the end of the shaft off with high precision. Each jaw may include a lever arm extending from a second end thereof configured to receive an application of a user force to overcome the spring bias force to enable the set of jaws to be separated for mounting the shaft therebetween.

A reciprocating saw blade mounting device includes a reciprocating rod, a clamping mechanism and an ejection mechanism. The reciprocating rod is provided with a clamping cavity. The clamping mechanism includes a clamping member and a positioning member which are disposed opposite to each other. The clamping member can move such that the reciprocating saw blade mounting device switches between a clamping state and a released state. The ejection mechanism includes a pressing block and a first elastic member. When the reciprocating saw blade mounting device is in the released state, the pressing block is elastically pressed between the clamping member and the positioning member by the first elastic member. When the reciprocating saw blade mounting device is in the clamping state, the pressing block is pressed out from between the clamping member and the positioning member by the clamping end and compresses the first elastic member.

A hand operated cutting tool (200) for pipes or tubes includes a housing (202). The housing (202) defining at least one first opening (204) to receive an object (210) to perform a first cutting action, and a second opening (206) which is adapted to perform a second cutting action. The first opening (204) includes a longitudinal axis (A-A1) and the second opening (206) include a longitudinal axis (X-X′). The longitudinal axis (A-A1) and the longitudinal axis (X-X′) include an angle (Z) therebetween that is unequal to 0 degree. And, one or more cutting blades (208, 502) are operatively coupled to the first opening (204) and the second opening (206). The one or more cutting blades (208) is arranged such that it is performing both the first cutting action and the second cutting action.

A cutting tool for cutting pipes of varying diameters includes a body having an opening extending along a predetermined axis through the body, and a cutting blade extending into the opening along a plane extending at right angles to the predetermined axis. The body includes a plurality of pipe support members, which are spaced from one another and configured to contact an outer surface of a pipe received by the tool, and a plurality of flexible connection members that connect the pipe support members to one another.
