Protecting the Head
If you wish, you can put masking tape on the sides and front of the key to protect it from the dreaded ebony dust. This may make cleanup of the key somewhat easier. You should tape off the top of the key from the 3rd score line back. This is to protect those lines from the sandpaper that we'll use to round the key head. You can see the two notches we cut at the top of the head. The notches actually become the top of the rounded part of the key head. They eliminate the need to use the shoe-shining technique close to the score lines - we want to keep them crisp.
