(Thread title refers to the tool, not to me. I may be an oddball, but I'm well known as an oddball!)
The tool looks like some sort of a household combination from the late 1800's. I'm seeing pliers (with stove-pipe crimpers in the jaws), a hammer, wire cutters, and a jar opener. There is a nail puller claw at the end of one handle, and possibly some type of can opening device at the end of the other. Length = about ten inches, made from heavy cast malleable iron by the looks of it. The box-type plier joint is unusual. Only markings are PAT APPLD FOR.
