It's useful.

This happened the other day when I sneaked into Mayhem's shaping room to design the tail of a new board design.

First, cut off the hand-drawn pencil outline with a saw. So, when I looked closely at the saw I was using,

The words "nishii kouzii" were written on it with a label maker.

Ah, that reminds me. This was when Mayhem came to Japan six years ago and came to shape his body. At that time, he asked me to lend him my saw, and this is what I gave him. I was happy to hear that you use it every day. It must be useful. But this is something I used in my home economics class in junior high school! (lol) I forgot but now I remember!
