Modern firearms are typically designed to be disassembled for routine maintenance, modification and/or repair. Specialized tools are often required for disassembly and subsequent reassembly. As such, many separate tools may need to be readily available to accommodate the different component parts of one or even a multitude of different firearms.
Those that have a need to disassemble and assemble firearms may be constantly on the go and may also have additional tool needs, such as for survival purposes. In this regard, firearm repair and modification does not always take place in environments with access to many resources or storage options. Having to transport numerous tools can be cumbersome and can preoccupy valuable space, such as in a rucksack or bug-out bag. Moreover, the loss of even one of the many tools that may be needed can hinder a mission or jeopardize a survival situation. Therefore, there is a need for a multipurpose tool that can perform a multitude of functions relating to firearms and beyond.
In an aspect of the present disclosure, a multipurpose tool includes a handle, a body, and a first set of pins. The body extends from the handle and has a first side, a second side, and an opening that extends through the body from the first side to the second side. The first set of pins removably connect to the body so that the first set of pins are arranged along and adjacent to at least a portion of the perimeter of the opening and project away from the first side of the body.
Additionally, the first set of pins may be press-fit to the body. The plurality of pins may include no more than three pins. Also, a second set of pins may be connected to the body. The second set of pins may be arranged along and adjacent to at least a portion of the perimeter of the opening and may project away from the second side of the body. The second set of pins may be removably connected to the body, and the first set of pins may extend through the body so that they also extend from the second side of the body when fully seated. The opening may form a notch in the body and may include a first portion and a second portion in communication with the first portion. The first portion may form a partial circle, and the second portion may have first and second flats disposed opposite and parallel to each other.
The multipurpose tool may also include a modular hammer that is removably connected to the body. The modular hammer may include at least one hammer anvil and a set screw configured to removably connect the hammer anvil to the body. The set screw may include an outer thread, the hammer anvil may include a threaded opening, and the body may include a threaded opening. The outer thread of the set screw may be threadedly connectable to the threaded openings of the body and hammer anvil. The body may include a boss that has a boss base. The threaded opening of the body may extend through the boss base and into the boss. The hammer anvil may have a lower surface that bears on the boss base when threaded to the set screw. The boss may have a cross-sectional dimension greater than a maximum width of the body. The hammer anvil may include flats disposed at opposite sides of a longitudinal axis thereof. The modular hammer may include a plurality of hammer anvils in which at least three hammer anvils of the plurality of hammer anvils each have a differently configured end comprised of one of a single flat surface, spherical shape, wedge shape, conical shape, and hour-glass shape.
The multipurpose tool may also include a notch and a cutter removably connected to the body and disposed within the notch, the removable cutter may have a V-shaped blade. The cutter may be connectable to the body via a threaded fastener. The tool may also include a bottle opener that has a hook shaped nose that projects outwardly from the body and over a portion of the notch. The body may be integrated with the handle so as to form a monolithic structure. The multipurpose too may include a magnet embedded within one of the handle and body.
The multipurpose tool may include at least two or more, at least five or more, or at least ten or more of a hex tool, bottle opener tool, barrel bushing removal tool, spanner wrench tool, muzzle device tool, cutter tool, bit driver tool, receiver extension tool, castle nut tool, tri-lug tool, square socket tool, hammer tool, box wrench tool, fire striker tool, screw driver tool, and open slot wrench tool.
The features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings in which:
Tool handle 102 includes finger notches or grooves 106, a palm swell 108, jimping 114, and one or more open slots 103. Open slots 103 reduce the weight of tool 100 and also allow for a paracord or lashing which the user can attach to their wrist to help maintain positive control of tool 100 particularly during hammering, as discussed below. Finger notches 106, jimping 114, and palm swell 108 further assist with positive control and also help designate a desired grip position. Thus, while it is preferable to have such features for optimal operation, some embodiments of tool 100 may not include either of the finger notches 106, jimping 114, palm swell 108, or open slots 103.
