Before the Undo Command, There Was the Electric Eraser

I owned a little battery-powered, handheld electric eraser when I was in middle and high school. It cost maybe ten dollars, and it was so great. Amazing precision and super effective -- way better than the eraser nub at the end of a pencil. Would recommend.

&gt; The Dremel Moto-Tool, introduced in 1935, came with an array of swappable bits.<p>I&#x27;m kind of impressed at how those bits look pretty much identical to what you&#x27;d get today, and from the looks of it, they would fit in a modern Dremel rotary tool.

I <i>dreamed</i> of having one of these when I was in high school drafting class!<p>They definitely were worth it over “acoustic” erasers, but cost something like $70. The few times I got to use one spoiled me.

They were great! Along with the drafting machine instead of T-square and triangles.<p>This is a reminder of so many things: Like chip and board &quot;tape out&quot; being done with actual tape on velum...
