According to Wikipedia’s description, an agraffe is “a part found on some pianos. The agraffe is a guide at the tuning-pin end of the string, screwed into the plate, with holes through which the strings pass. It anchors the strings, ensures proper height and determines the speaking length of the string.”

I should have taken photos before polishing them. It is like polishing an old penny, to make it look shining like new. Since the materials are similar, this must be a good example.

Anyways, working on such a small part is pretty hard and it took hours to polish just fifty-four of them. This is like I do one step per day on this piano rebuilding.
