A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.

An object of the present invention is to provide a replaceable-blade-type saw in which a handle fitting part can be insertably engaged in a guide member even if the width dimension of the handle fitting part is greater than the width dimension of the guide member. In a handle fitting part 3 of a saw blade 1 is formed a slit part 8, which is configured from a first slit part 6 formed inward from the side edge part of the handle fitting part 3, and a second slit part 7 formed as a continuation of the first slit part 6 as well as being formed toward the distal end side of the handle fitting part 3 from an inner end part 6A of the first slit part 6, and a slit outer-side part 9 positioned on the outer side of the slit part 8 of the handle fitting part 3 is elastically moved or elastically deformed inward by the slit part 8 when bearing external force exerted inward from the side-edge-part side.

An accessory for an oscillating power tool includes an attachment portion configured to be coupled to an oscillating power tool and a working portion coupled to the attachment portion and extending generally along a longitudinal axis. The working portion has a generally planar wedge shape bounded at least partially by a rear non-cutting end with a first width, a front cutting edge opposite the rear edge with a second width that is greater than the first width, a first side cutting edge extending from a first end of the rear end to a first end of the front cutting edge at a first angle to the longitudinal axis, and a second side cutting edge opposite the first side cutting edge and extending from a second end of the rear end to a second end of the front cutting edge at a second angle to the longitudinal axis.

A blade extension for a reciprocating saw comprises a movable member and a stationary member. The movable member has a proximal end, a distal end and a body extending between the proximal end and the distal end. The proximal end comprises a blade end shaped to be received in a blade holder of the reciprocating saw. The distal end is configured to be coupled to a reciprocating saw blade. The stationary member extends along at least a portion of the movable member and supports the movable member for movement relative to the stationary member. The stationary member has a proximal end configured to be coupled to the reciprocating saw and an opposite distal end. The distal end of the movable member is arranged to protrude distally beyond the distal end of the stationary member.

A reciprocating saw includes a housing, a motor, and a drive mechanism. The drive mechanism includes a driven gear that is rotated by the motor. The driven gear is vertically-oriented within the housing. The drive mechanism also includes a drive arm coupled to the driven gear to translate rotary motion of the driven gear into reciprocating motion, and an output shaft coupled to the drive arm to reciprocate relative to the housing along a spindle axis through a cutting stroke and a return stroke. The drive mechanism further includes a counterweight coupled to the driven gear for rotation with the driven gear. The counterweight moves toward the spindle axis during a start of the cutting stroke of the output shaft and moves away from the spindle axis during a start of the return stroke of the output shaft.
