I dreamed of having one of these when I was in high school drafting class!

They definitely were worth it over “acoustic” erasers, but cost something like $70. The few times I got to use one spoiled me.

> The Dremel Moto-Tool, introduced in 1935, came with an array of swappable bits.

I'm kind of impressed at how those bits look pretty much identical to what you'd get today, and from the looks of it, they would fit in a modern Dremel rotary tool.

They were great! Along with the drafting machine instead of T-square and triangles.

This is a reminder of so many things: Like chip and board "tape out" being done with actual tape on velum...
