This is a very nice machinist utility scraper that can be used as a bearing scraper and other applications too  The steel is triangular in shape with basically 4 working surfaces if you include the end cutting edge surface.  The width at the end cutting edge is 1/2" and the overall length of the tool is 11" long.  It's made of very good hardened steel.  Very clean, no rust, no damage, good solid hardwood tanged type handle with good ferrule.   A very useful machinist scraper tool!  There might be a maker's mark on the tang  part of the tool, but not that can be seen attached to the handle.
