In the making process of woodworks work, I used sandpaper from before. Polishing of woodworking which can not be done with sandpaper from friends was taught to use a file dedicated to woodworking, purchased Tsubosan / Demon File (woodworking type). It can be roughly cut on the face of the ogre and finished in a fine plane on the opposite side. At the same time, we purchase Tsubosan · file file wood pattern · medium (M) and use it. Push this file up to the front (front) and cut it. When pulling it lightly pull, you can cut it when pushed forward. DIY's work has become a must-have tool. Everyone please try it. I knew the metal file, but the file only for this woodworking is the recommended tool.
