A multi-use ax may comprise a head and a handle, each comprising multiple functionalities. In various embodiments, the head and the handle may comprise functionalities such as an anchor and attachment point, or belay loop, to allow a user to bail out of a hazardous environment. In various embodiments the head and/or the handle may comprise functionalities to provide a means by which a user may shut off gas and/or water at various sources.

A multi-purpose tool and a method for use thereof, where the multi-purpose tool includes a first component having a first shaft and at least one first tool affixed thereto and a second component comprising a second shaft having at least one second tool affixed thereto, the second shaft being substantially hollow and capable of slidably receiving the first shaft. The multi-purpose tool further includes a quick-securing mechanism disposed along the length of the second shaft including a dial that is rotatable relative to the second shaft and having a threaded portion affixed to the dial. The quick-securing mechanism is configured to move a pin into an extended position when the dial is rotated in a first direction, and to move the pin into a retracted position when the dial is rotated in a second direction. The pin interacts with one of at least two holes in the first shaft to secure the first shaft in either a compact or extended configuration relative to the second shaft.

A power door opener including an actuator having a housing with an electrically powered actuator shaft that can be extended from a closed to an extended position. In one embodiment, a movable push plate is affixed to the actuator shaft and a fixed push plate is fixed in its position with respect to the housing. In the closed position of the actuator shaft, the fixed and movable push plates are aligned to form a combined edge for insertion into the space between a door and door jamb. The actuator shaft extends to move the movable push plate apart from the fixed push plate to spread the space and release the door from the door jamb. Alternatively, a double ended power door opener is located between opposite door jambs and the extending of the actuator shaft forces the door jambs apart to release the door from the door jamb.

A shear blade (2) is for a portable hydraulic cutting device, such as a rescue device having a blade body (9). The blade body (9) has an assembly region (18) and a cutting region (15), a cutting edge (16) in the cutting region (15), a contact surface (13), located on one side of the cutting edge (16), for an additional shear blade. An outer surface (14), located on the other side of the cutting edge (16), is provided to act on the object to be cut. The cutting region (15) has a recess (22) for receiving a cutting insert (21). The recess (22) is configured such that the cutting insert (21) is insertable into the recess (22) at an acute angle to the contact surface (13) of the shear blade (2).

A shear blade is for a portable hydraulic cutting device having a blade body. The blade body has assembly and cutting regions, with a cutting edge in the cutting region. A contact surface is on one side of the cutting edge for an additional shear blade. An outer surface on the other side of the cutting edge acts on the object to be cut. A first surface portion of the outer surface extends away from the cutting edge along an orthogonal, which meets the contact surface at the cutting edge, or at an acute angle relative to the orthogonal. A second surface portion connects to the first surface portion at an acute angle to the orthogonal. A third surface portion connects to the second surface portion at an acute angle to the orthogonal. Angle is smaller than angle , which is smaller than angle .

A survival rescue multi-tool device is provided in a single planer body constructed and arranged to have incorporated therewith multiple hand tool configurations and an overall curved ergonomic formation.

A rescue system includes a mobile rescue device, in particular a spreading device, a cutting device, or a combined device having a spreading and a cutting function, including a base body with a handle, a working device arranged at the base body, a controller for controlling the work sequence of the working device, and an input device arranged at the base body for inputting control commands into the controller. Furthermore, an external additional input device is formed, which is structurally independent of the mobile rescue device and coupled or couplable with the controller of the mobile rescue device by a data transmission device.

A plier having multiple functions includes a fixed leg having a pivot point, a fixed handle on a first side of the pivot point, and an upper jaw on a second side of the pivot point. The plier further includes a moveable leg rotatably coupled to the fixed leg at the pivot point and having a moveable handle on the first side of the pivot point and a lower jaw on the second side of the pivot point, the lower jaw defining a spanner extending away from the upper jaw.
