What was a better invention: the eraser or the paper clip?

@DragonFruit but white out is more work. I mean, you can also use a redactor felt pen too for that matter

@atlantic59 Wite-out is more work than an eraser???!!! I don't think so....but you also made my point (there are other options that work easily as replacements for an eraser.

@DragonFruit yeah you got a point, maybe not more work in terms of arm and hand movement
