Changing how you play.
WITH GREAT POWER .... Comes a little bit of responsibility.
Silicon nitride is an amazing super-ceramic. It is as hard as sapphire and does not bend. As such, if hit hard enough while extended, it could break. Be careful especially not to hit the tip from the side if the endpin is extended. It might be a good idea to walk around busy places with the endpin retracted. Don't worry though, this robust endpin has been thoroughly tested and will not break under normal playing circumstances.
