The present invention provides a blade-replaceable cutting tool, which includes: a first handheld portion and a second handheld portion; the second handheld portion is rotatably connected to the first handheld portion; and further includes a blade mounting plate and a blade, the blade mounting plate is rotatably mounted to the first handheld portion; the blade is detachably mounted to the blade mounting plate. Wherein, the blade mounting plate and the blade may be replaced with a ratchet blade which is detachably and rotatably mounted to the first handheld portion.

A cutter, such as a tubing cutter or a swing cutter. The cutter may include a cutting wheel; a roller; a housing assembly including a first housing portion supporting the cutting wheel and a second housing portion supporting the roller; a shaft connecting the housing portions, rotation of the shaft causing relative movement of the housing portions along a shaft axis; and a knob connected to the shaft and engageable by a user to rotate the shaft, the knob having, in a plane perpendicular to the shaft axis, a non-symmetrical shape defined by opposite circular sector portions and opposite lever portions, each lever portion being engageable by a user to apply a force to the knob in a direction of rotation. The cutter may include a shaft with a radial shoulder preventing movement of the shaft from the cavity through an opening in the housing portion.

A tool is configured for preparing an end of a pre-insulated tubing bundle having a central tube having a diameter and an outer insulation covering have a diameter. The tool includes a body having first and second body sections joined to one another and movable between an open position and a closed position. The body sections, when joined to one another define a circular central opening. The circular central opening has a diameter about equal to the diameter of the outer insulation covering. A cutting blade is positioned in one of the first and second section sections extending inwardly of the circular central opening a distance equal to one-half of a difference between the diameter of the outer insulation covering and the diameter of the central tube.

A cutter and a kit. The cutter, such as a close quarters cutter, is operable to cut a work piece extending along an axis and includes a cutting wheel, a roller, and a housing assembly supporting the cutting wheel and the roller for movement about the axis in a cutting direction to cut the work piece. The housing assembly has a generally cylindrical outer surface engageable by a user to pivot the cutter about the axis. A grip portion is provided on the outer surface and includes a plurality of grip members. Each grip member includes, relative to the cutting direction, a trailing surface and a leading surface extending from the outer surface. The leading surface may be angled toward the cutting direction.

Wherein, the blade mounting plate and the blade may be replaced with a ratchet blade which is detachably and rotatably mounted to the first handheld portion.

A tube cutter includes a main body, a holder slidably mounted on the main body, a guide bolt rotatably mounted on the main body and locked onto a lower portion of the holder to drive and move the holder forward or backward by rotation of the guide bolt, and a driving handle removably mounted on the guide bolt to drive and rotate the guide bolt, and to enhance the torque of the tube cutter.

A cutting tool having multiple functional faces and an adjustable blade. The cutting tool may include a solid body having multiple functional faces, a blade, and a peg. The multiple faces of the solid body may include a cutting face, a gripping face, a base face, one or more securing faces and a pressure face. The cutting face may be curved and may form a receiving bay for receiving an item to be cut and may include a plurality of slots. The blade may be secured in any one slot of the plurality of slots. The peg may help to secure the blade within the cutting face. The cutting tool may also include a compartment for storing extra blades.

Each grip member includes, relative to the cutting direction, a trailing surface and a leading surface extending from the outer surface. The leading surface may be angled toward the cutting direction.

A tube cutter includes a handle, a carrier, a circular knife, a knob, a threaded rod and a spring. The handle includes an aperture. The carrier is movably connected to the handle, and includes a screw hole. The circular knife is supported on the carrier. The knob is rotationally connected to the handle and includes a non-circular recess. The threaded rod includes a threaded section inserted in the screw hole, a shank inserted in the aperture, and a non-circular head inserted in the non-circular recess. The spring is compressed between the handle and the non-circular head to render the threaded rod smoothly movable relative to the handle.

A cutting tool includes a housing, a motor positioned within the housing, a pipe holder formed in the housing, a blade pivotally coupled respective to the pipe holder at a pivot point for movement relative to the pipe holder during a cutting motion, a drive mechanism including a first gear, and a quick-change mechanism rotationally coupling the blade to the first gear. The quick-change mechanism is operable to selectively de-couple the blade from the first gear to remove the blade for replacement.
