Because I still see this happen at pickups and tournaments.
Just want to remind players that riding around with a broken (carbon) shaft is extremely dangerous. This should be an absolute no-go.
If you deem the situation requires you to continue to play, drop the broken shaft before you continue.
Also make sure to get rid of broken mallets in a safe way. Throwing it above the visible crowd into the nirvana is not safe!
Please don´t continue playing with a broken shaft if your mallet happens to break midgame. Might as well ride around with a spear in your hand. Horrible incident waiting to happen.
Refs, please immediately and vehemently stop the game if you notice a player continuing to play with a broken shaft.
And while we are at it, don´t throw your broken mallet pieces recklessly out of the court (into the crowd) either.
