A cutting tool includes a fixed blade having a cutting surface and a movable blade having a cutting surface. The movable blade is rotatable between a receiving position in which the cutting surfaces are spaced and a cutting position in which an object disposed between the fixed and movable blades is cut by the cutting surfaces. A return spring member is connected to the movable blade. The spring member stores energy when the movable blade is rotated from the receiving position to the cutting position. The spring member returns the movable blade to the receiving position when the stored energy is released.

A blade-replaceable cutting tool includes: a first handheld portion; a second handheld portion rotatably connected to the first handheld portion; a cutting structure rotatably connected to the first handheld portion, the cutting structure including a blade mounting plate rotatably mounted to the first handheld portion and a blade detachably mounted to the blade mounting plate; and a locking mechanism configured to lock the blade on the blade mounting plate when in contact with the blade, and to unlock the blade when separated from the blade, so that the blade can be detached from the blade mounting plate.

A tool for removing an outer jacketing material from a corrugated tubing. The tool includes a tubular housing with a first end having a bore extending therein for receiving the jacketed corrugated tubing and a second end with a tool connector. A blade is fixed through an opening within the housing near the first end. As the jacketed tube is pushed into the bore, the blade engages the jacketing material without scoring the corrugated tubing. Rotation of the tubular housing via the tool connector along with inboard movement of the tubing within the housing bore further engages the blade with the jacketing material. As the jacketed tubing is moved into the bore, the blade circumferentially removes the jacket from the tube. The blade is configured and positioned so as not to engage the corrugated metal tubing from which the jacket is to be removed.

A tubing cutter configured to cut spine-fin tubing includes a pair of cutting heads pivotally connected and movable between an open position and a closed position. Each cutting head of the tubing cutter includes a blade edge having an arcuate portion with a radius less than an outer radius of a tube of the spine-fin tubing.

A pipe cutting device includes a cutting element, a counter-holder, and a C-shaped working head. The counter-holder is formed by the working head and the cutting element protrudes into a C-opening. The working head merges into a foot part and the cutting element is accommodated in a displacement part. The displacement part is movably arranged with the cutting element in an offset part and/or the counter-holder has rollers, and each two rollers are mounted in pairs on a rocker part. A further pipe cutting device has an offset part and a counter-holder which are formed on a C-shaped working head. The working head merges into a foot part which can also be used as a handle area, and the offset part can be offset relative to the foot part in order to change an opening width of the working head. In addition, the offset part has a cutting element.
