A must have for picture frame making
as accurate as my starrett square. appears to a precision addition to my tool box.
Not up to par
I have always known Starrett to sale top of the line tools, and I have many of their squares/rules. I thought I would get the same precision with this, but that was not the case. The zero line on the outside ring looks like it was sloppily stamped into the cast iron. The line is more than twice that of the measurements on the inner ring, which makes it impossible to get an accurate read. So if you want to recreate an angle, you can't. Very inaccurate.
