When I started engineering school in 1958, I got a very nice large set of German nickel silver drafting tools. But my experience and working with other engineers led me to buy and use Vemco center bow compasses, drop bow compasses and beam compasses. Back then, Vemco was made in USA and well suited to professional use. Lots of them on eBay.

I had Dad's K&E's from his first year at Uni, 1926. But he later said he had bought them used! We were to buy French & Vierck. I had French, same source. Instructor took it home overnight to compare, said it would do fine, so I saved a few scarce bucks!
My era, we jumped on Rapidographs vs steel-pen tips. Young "Engineers" putting on airs sported them in pocket protectors. Draftsmen just snickered at those guys trying to write a check with the Rapidograph held dead-nuts vertical!
We bought "Osmiroid" calligraphy pens to sign with a flourish, get AWAY from single-stroke.. and not have the silly Rapidograph leakage ruin all our white shirts!
Any shirt but white was still heresy, East-Coast, of course. We herd rumours Californios had invented surfing, sex, "casual" clothing and had even ceased wearing narrow black ties. Figured all that too outrageous an improbability to be true.
It soon became the newer fad to use wax transfers for classy lettering. Then pragmatism returned with a special ball for Selectric Typewriters - "Orator" I think it was called. That typeface was close enough to single-stroke Gothic we could just let a typist do the legends and text for a whole team, cut and hot-wax on as a block.
"Snopake" covered for the changes - everything gone "camera ready" and blackline Ozalid by then rather than "blueprint".
There's an intermediate step for the many among us who find a parallel rule and a handful of triangles and templates faster for the quick and dirty than CAD.
'puter-edit and print PART of what yah need with the Pee Cee, do the actual shapes by hand, cover for changes with more paper overlaid - or the "snowpake" -> scan it, save file as .tiff or .png, print as needed.
