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 device for cutting the foil on a bottle, including a circular shaped body that has a top end and a lower end, wherein the body includes a lip at the top end that protrudes inward such that it can rest on top of the mouth of a bottle, and a plurality of cutting elements attached to the lower end of the body on the inside, such that when the outside of the body is pressed by the hand of a user the cutting elements make contact with foil wrapped around the top end of a bottle, and where the distance from the top end of the body to the lower end is sufficient to enable the cutting elements to make contact with the foil below the bead of the bottle.

A cutting tool is configured to cut a tube. The cutting tool comprises a tube cutter. The tube cutter includes a housing having a blade opening and a profile defining a tube opening configured to receive the tube. The tube cutter also includes a blade arranged in the blade opening and extending into the tube opening. The cutting tool further comprises a handle having a grip portion and a mounting portion, the mounting portion configured to removably attach the tube cutter to the handle. The cutting tool also comprises a ratcheting mechanism configured to alternatively lock and unlock the tube cutter for rotation with the handle. When the tube cutter is attached to the mounting portion, the tube is arranged in the tube opening, and the handle is rotated in a first direction about the pipe, the ratcheting mechanism locks the tube cutter for rotation with the handle, such that the tube cutter rotates with the handle and the blade cuts the tube. When the tube cutter is attached to the mounting portion, the tube is arranged in the tube opening, and the handle is rotated in a second direction that is opposite the first direction about the pipe, the ratcheting mechanism allows the handle to rotate relative to the tube cutter.

A cutting tool includes a housing having a blade opening and a biasing member having a securing portion, an engaging portion, and a semi-circular body portion in between the securing portion and the engaging portion. The securing portion secures the biasing member to the housing within the housing and the engaging portion extends away from the body portion. An annular blade is biased by the engaging portion towards the opening and against the housing, with the blade at least partially extending through the blade opening.

Devices and methods for bending or cutting implants are disclosed herein. In some embodiments, an instrument can include a rotatable drive shaft that urges first and second portions of a modular bending or cutting template toward one another to bend or cut an implant disposed between the template portions. A linkage assembly can be included to provide a mechanical advantage in urging the template portions toward one another. In some embodiments, an instrument can include a rotatable drive shaft that, depending on direction of rotation, pushes or pulls a first modular template portion with respect to a second modular template portion to bend an implant disposed between the template portions in one direction or another direction. In some embodiments, an instrument can include a worm drive that rotates a cutting wheel with respect to a cutting plate to cut an implant inserted through openings formed in the cutting wheel and the cutting plate.

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.

A C-type tubing cutter is described that accommodates and cuts a range of tubing or workpiece sizes. The cutter includes a radially positionable roller carriage that can be selectively positioned in one of several predetermined positions corresponding to different tubing sizes. The cutter also includes a trigger that can be engaged with the roller carriage to lock the carriage in a desired position. Certain versions of the cutters also utilize arcuate slots or tracks along which a cutter wheel is positionable.
