Sorry @Duane
I gotta call BS on this one. Tools (whether good or not) become defunct when their utility is supplanted by a more innovative instrument. This is generally a common occurrence nowadays as technological advances impact our lives continually. I daresay that, with the notable exception of the pencil, just about every tool in Wright’s repertoire is no longer in use to any significant degree. Hardly any architect, engineer or draftsperson still uses a tee square, triangles, beam compass, protractor, drafting scales, erasers. pen, ink, or vellum today.
If I still use it?
Once in a while, yes. For taking quick notes. Not accurate drawing.
-It holds on to the paper in windy, difficult conditions.
Bit annoying though that the standard-holes in the paper don’t fit!
More appropriately, we called 'em “scumbags” and while working as an architectural intern many years ago, my coworkers also took great delight in tossing them around the office (with somebody’s head or backside as the primary target).
