Abstract: A multi-track nail insertion tool that contains two or more tracks for holding nails allows the user to use a single tool for inserting a variety of sizes of nails. The multiple tracks allowing the user to load a variety of sizes of nails during a single loading process. The user would then adjust the multi-track nail insertion tool to select the desired nail size. The multiple tracks or reservoirs can be selected by rotating the multiple tracks, sliding the multiple tracks, selecting one of multiple insertion mechanisms, and adjusting the position of the nail insertion applicator. The reservoirs can be designed whereby one reservoir can support one nail gauge size and a second reservoir can support a different nail gauge size. An alternate can include a design that is adjusted or with replaceable components to provide the ability to change nail gauge sizes.
