The hole is already made during this process (Eye) punched out for the stem. Casting seams are removed and the surface smoothed by grinding on appropriate machines. Then comes the hardening, a job, which requires a lot of experience. It must be the point – sufficiently hard, but without being brittle – to be hit.
