When you hammer a blade, you are putting tension in the steel. Every time the blade is hit with the hammer the more tension is put in the steel. IIRC the faster the blade speed the more tension you need on the outside of the blade. When the blade spins it causes it to expand. That is what hammering does. It controls expansion. When it heats up the blade expands more then you loose your tension. When the sawer is done with my blade it will be completely sraight edge flat.

He is so busy it will take 2 months to gat my blade back. I do trust him with my life.
