Abstract: A hammer punch tool having a guide and a punch that is slidably coupled to the guide. The guide has a force transfer surface and a cavity accessible through an opening in the guide. The punch has a portion that is slidably received within the cavity of the guide through the opening in the guide. The guide slides relative to the punch between a reset position of the guide (or extended position of the punch), in which a portion of the punch engages the guide to retain at least a portion of the punch within the cavity, and a hammer position of the guide (or retracted position of the punch), in which the force transfer surface of the guide engages the punch. A method of forming material with the hammer punch tool by striking the punch with the guide.

Abstract: A ring sizing tool with a base and a guide movably coupled to the base. The base has first and second ends with a longitudinal axis extending between the ends. A cut guide surface is positioned adjacent the second end, and a base ring engaging surface is spaced apart from the cut guide surface. The guide has a guide ring engaging surface and at least one ring size indication spaced apart from the guide ring engaging surface. The guide is movable with respect to the base in a direction aligned with the longitudinal axis of the base between at least a first position, in which the guide ring engaging surface abuts the base ring engaging surface, and a second position, in which the guide ring engaging surface is spaced a distance from the base ring engaging surface. A method for sizing a ring with the ring sizing tool.
