Keith,
I own one "true machinist straight edge" and really don't like it. But now I can appreciate the value in having such an edge. It sure is easier to shave off a small amount of metal from a knife edge than from a 3/8" flat. It would also better deal with a non-flat edge on the thing being tested.

Hi Rick
I can understand that, something you can get off the local market.
CRS might work fine,it is smoother than HRS , there is no scale on it.
A true machist straght edge are thick ,but with like a knife edge.
They are about 3/8 thick x3-4in wide with one edge machined to
a taper to 1/8in or less.The thin edge is trued up.
