Eraser? Try Breadcrumbs

According to General Pencil, until 1770 bread crumbs were used as erasers.

That would be easier for me. Of course, I'd need to perfect how I bake bread.

That being said, erasers weren't even attached to pencils until 1858.

If it had been done much earlier, too many people might have gotten slivers in their teeth from trying to ingest the eraser.
