Devices, systems, and methods for a segmented tool include a connection system for selectively connecting segments together for use. The connection system can be collectively formed of complementary portions of the segments which can be interlocked together to block against disconnection.

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.

A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction 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 reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.

In some embodiments, a blade sheath device may include an elongated body having a mouth and a terminus. A central depression may be disposed on a first side of the body and may extend between the mouth and terminus. A perimeter lip may extend around portions of the central depression. An optional handle guard may be positioned proximate to the mouth, and may extend away from the mouth. A retaining cover, which may be coupled to the perimeter lip, may extend over portions of the central depression. One or more magnet elements may be coupled to the body proximate to the central depression. A securement fastener may be coupled to the device on a second side of the body. Optionally, the device may comprise one or more apertures which extend through and between the opposing sides of the device, such as through the body and/or through a handle guard.

A massager having a shaft with a blade that allows the massager to be coupled to a conventional jig saw. The massager has a massage head that is shaped to provide massaging and is secured to a mounting flange using a ball interconnect and a washer. The blade has an end configured to engage the blade receiving mechanism of a conventional jig saw. Operation of the jig saw imparts reciprocal movement of the massage head for massaging activities.
