An auxiliary handle is for use with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, and a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch. When the first protrusion of the first clamp engages the first notch, the second clamp is movable along the shaft between a first position, in which the second protrusion engages the second notch, and a second position, in which the second protrusion is disengaged from the second notch. The auxiliary handle also includes a grip coupled to the shaft. When the grip is rotated relative to the second clamp, the second clamp is moved from the second position toward the first position.

A dental instrument is configured to reduce user discomfort and increase control over the surgical edge of the instrument. The invention further discloses a dental instrument having a replaceable blade.

The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch, and a grip coupled to the shaft. When the first protrusion of the first clamp engages the first notch and the grip is rotated relative to the second clamp, the second clamp is moved toward the first clamp, such that the first protrusion engages the first notch and the second protrusion engages the second notch to couple the auxiliary handle to the housing of the power tool.

A tool is provided that includes unitary plate that includes a blade portion and a tang portion. The blade portion can include an edge. The tang portion can include a positioning hole, a first hole, a slot, a second hole, a rivet hole, and one or more teeth (also referred to as one or more barbs) on a side of the tang portion. The tool can further include a hilt member which includes a through passage, a tab, and a notch. The tool includes an overlay on a body to create a handle for gripping the tool. The tool further includes a hammerhead cap on an end of the body, the hammerhead cap is coupled to the handle with a rivet through the rivet hole.

A power tool assembly includes a hand-held power tool, a dust collector removably coupled to the power tool, and first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

A socket drive assembly for rotating a fastener with 360.0 degrees of rotation includes a wrench that has a first end and a second end. A socket drive is coupled to the wrench and the socket drive extends along an axis that is oriented perpendicular to the longitudinal axis of the wrench. The socket drive includes a inch drive and a inch drive for engaging either a socket or a socket. A handle is removably coupled to the wrench and the handle is oriented to rotate about an axis is oriented perpendicular to the longitudinal axis of the wrench. In this way the handle facilitates the wrench to be rotated 360.0 degrees around a fastener that is loosened or tightened.

An exercise device having many advantageous features is described, including the ability to provide a user with multiple modes of training by transforming the device into different configurations. Users can exercise their cardiovascular endurance by using the device in its jump rope configuration. Users can also engage in muscular resistance training using the same device configured to one of multiple possible resistance training configurations. Resistance training configurations provide a method of suspending a user's bodyweight from an anchor point such that a user can train their muscular strength capacity by exerting themselves against the force of gravity. Resistance can be selected from nearly zero resistance to the user's full body weight, with the ability to easily adjust between exercises and between users, and the ability to easily transform the device between configurations to provide for versatility and ease-of-use. The device includes an inelastic length member with two handles and/or grips at both ends. In one embodiment, the device also includes handles that can be detached from complimentary clips located at the terminal end points of the inelastic length member such that the clips can secure to each other or to designated points on the inelastic member for the purpose of easily transforming the configuration of the device. This multipurpose, portable exercise device is compact and can be used to perform jump rope exercises or bodyweight suspension exercises. To perform jump rope exercises, users can manipulate the handles to exert a centrifugal force on the device to swing the inelastic member about their body. Users can perform bodyweight suspension exercises after securely mounting the device to an anchor point by and subsequently pulling or pushing one or both of the grips away from the anchor point.
