I bought this for my machining class; used it all of two class periods. Got a rap on the knuckles from the teacher who said, "I told you to get a FLEXIBLE steel rule!" This one is rigid. So it's for sale. Those 100ths lines are AWFULLY close together, just warning you...kinda hard to read. The top photo makes it look like some of the lines are missing on the 50ths scale, but that's just glare from the light, they're all there and very sharply etched, see bottom photo. $15 shipped in the continental US.
