This blade could have been used both for erasing mistakes on paper by scraping them away, AND for removing excess blood in people thereby lowering blood pressure. Although they probably did not know that was why people sometimes got better after this treatment.  George Washington died after it.  This tool is signed 'Miller Bros Cut (cutlery) Co. / Meriden'.  I believe that stands for Meriden Conn. Most of these I came across were not signed.  The blade on this one is symmetrical with a cutting edge on both sides. This item is an auction.  I have another similar listing with one in better condition as a Buy It Now, if you hate waiting.  Email if you have questions.

THE SMALL PRINT.  Shipping will be paid by the buyer. I mail fast because I really appreciate fast payment.
