I found this bar in my late father-in-law's shop. It could date back to his father who owned a landscape supply company in Seattle, or his wife's father who was in construction in eastern Washington. Researched on-line but couldn't find anything (too many Soderfors anvils.) It is 12 inches long by 1 and a half inches wide nd both long sides have 45 degree taper. Any ideas as to what it is?
