Abstract: The firearm cartridge extraction tool is used to open a jammed slide to extract a cartridge. The firearm cartridge extraction tool comprises a support frame, an arm, and a push rod. The support frame holds the arm above a work surface and provides a padded stop for the grip of the firearm. The arm may slide along a guide track to adjust for the size of the firearm. The arm holds the push rod in a position where it may align with the muzzle of the firearm. The pushrod comprises a main screw with a handle on one end and a swivel mounted male coupler on the other end. As the handle is turned, the main screw may push a socket located on the male coupler over the muzzle while the padded stop prevents movement of the firearm, thus forcing the slide to open.

Abstract: A preassembled display with automatic stackable supports (PDASS) is described. A PDASS may include two or more blanks (for example pieces of corrugated paperboard) that are joined together, for example to initially form a knocked down flat (KDF). The PDASS may include an insert formed from a single blank, where the single insert blank, when the whole display is erected, automatically erects and provides asymmetric supports that form at opposing corners of the outer blank.
