Abstract
A grinding pin (53) for notch grinding is provided. The grinding pin comprises a cylindrical region of formable grinding material and in which is formed a groove (18) for forming a notch. The length of the cylindrical region is such that further grooves (20) can be formed therein as each groove becomes too worn to form a notch.
