Eisen ran the knife over the surface of the wood and carved away at it. First things first, he had to get a proper, basic shape for brush-handle. Of course, that was not particularly hard, and within a few minutes, the old man was already done with that.
Then, he moved on to try to figure out what exactly he should turn this brush into when it comes to style. Immediately, he started to visualize something in the air in front of him with the use of his visualization skill. He changed the patterns around, the actual shape, certain details, and things like that.
And it really didn't take long for Eisen to come up with something good. First, he turned the piece of wood into the regular form that he wanted the brush to have. It wasn't really all that complex, but just something that would sit in this Soul's hand properly while he was painting.
