<P>PROBLEM TO BE SOLVED: To provide a repeatedly usable tool allowing use of a pencil to almost end of its lead while maintaining its good or better sense of use even if the pencil is shortened. <P>SOLUTION: The pencil extension tool to support a pencil is a wooden cylinder, which is approximately 16 cm in length and is approximately 1.4 cm in diameter. In each of the ends or one end of the pencil extension tool, a gentle conical hole with the depth of about 3 cm is formed toward the center of the cylinder so that a pencil is inserted into the hole. When the holes are formed at both ends, a combined use of a pencil and a colored pencil provides enhanced convenience. The pencil and the pencil extension tool are fixed to each other by frictional resistance using elasticity of them, which is the characteristics of the wooden one. Since the pencil extension tool is made of wood, a user can easily improve its sense of use by processing the tool with a cutting tool. The pencil extension tool and the pencil can be cut together, the pencil can be used substantially completely. <P>COPYRIGHT: (C)2012,JPO&INPIT |
