Geez Yumeko, overkill much on the knife?

Last I remember, she uses swords like Sakuya uses knives.

For a while I was wondering what she was cutting, then I realized she was using honing steel. It really looked like she was cutting into her own finger.

It did look like she was teaching Mai to peel potatoes. I didn't notice either till I had a really good look.
