Mastering, Repair
Your leader is using a stick in the winter made of hair. This is the stick of mastering and repair.
Imagine your leader holding this stick of hair in the winter, going around mastering all kinds of skills and repairing everything in sight. What a strange stick, giving even stranger abilities to its wielder.

What's the key to mastering any skill? A stick and a shoe (しゅう)!
Picture your leader again; stick in one hand, shoe in the other. He looks kind of threatening, like he's about to slap you with the stick and then throw the shoe at you. But that's what it takes for mastering certain skills. This is all for discipline’s sake.
