A blade cartridge for use with a surgical saw includes a bar and a rack. The bar includes a first holding feature for removably holding the bar static to the saw. The rack includes a base moveably disposed in the bar and has cutting teeth defining extending beyond the bar. A drive link extends from the base, providing a second holding feature for releasably engaging a reciprocating drive integral with the saw. One of the base and the bar includes a guide slot. The other of the base and the bar includes a static member extending into the guide slot. The guide slot and the static member allow the rack to reciprocally move from proximal to distal to proximal along a longitudinal axis of the bar. The bar includes two plates and a spacer between the plates. The base is located between the plates.

A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.

A multi-purpose handheld tool including a handle, a hatchet head portion, a saw blade and a saw blade control mechanism. The handle has a first end and a second end. The handle has a slot formed therein. The hatchet head portion is operatively coupled to the first end of the handle. The saw blade is pivotally coupled to the handle. The saw blade control mechanism pivots the saw blade between a storage configuration and a use configuration. The saw blade control mechanism includes a saw control handle and a saw control hub. The saw control handle has a gripping extension extending therefrom. The gripping extension indicates a direction of the saw blade with respect to the handle. The saw control hub engages the saw blade.

A tool includes a housing, a blade receptacle within the housing configured to receive a removable saw blade having a lock engaging region, and a blade release actuator adjacent to the blade receptacle, the blade release actuator being rotatable about an axis associated therewith and configured to selectively move a lock member into the lock engaging region. The blade release actuator comprises a ramp on which the lock member rests. Rotation of the blade release actuator rotates the ramp under the lock member from a blade locked position where the lock member is pushed by the ramp into the lock engaging region of the removable saw blade to a blade release position where the ramp is rotated to create a gap between the lock engaging region and the blade release actuator such that the saw blade is removable from the tool.

A reciprocating tool includes a reciprocation conversion mechanism disposed in a casing neck, a saw blade connected to the reciprocation conversion mechanism, a shoe, and a shoe adjustment mechanism. The shoe adjustment mechanism has a cover plate connected to the reciprocation conversion mechanism and a slide pin. The shoe has a support and a guide plate pivotably connected to the support. The guide plate is disposed between the cover plate and the reciprocation conversion mechanism. The guide plate has a slide groove parallel to a direction of reciprocation. The slide pin passes through the slide groove. In a locked position of the shoe adjustment mechanism the slide pin is engaged in the slide groove and the guide plate is locked by the slide pin. In an unlocked position the slide pin is disengaged from the slide groove and the guide plate is slidable in the direction of reciprocation.

A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

A ring sizing tool with a base and a guide movably coupled to the base. The base has first and second ends with a longitudinal axis extending between the ends. A cut guide surface is positioned adjacent the second end, and a base ring engaging surface is spaced apart from the cut guide surface. The guide has a guide ring engaging surface and at least one ring size indication spaced apart from the guide ring engaging surface. The guide is movable with respect to the base in a direction aligned with the longitudinal axis of the base between at least a first position, in which the guide ring engaging surface abuts the base ring engaging surface, and a second position, in which the guide ring engaging surface is spaced a distance from the base ring engaging surface. A method for sizing a ring with the ring sizing tool.
