<P>PROBLEM TO BE SOLVED: To provide a tool capable of easily cutting and dividing a cord-like backup material, which has a circular or polygonal cross section and serves as an underlayer of a sealing material, according to the width and depth of a joint, and also to provide the backup material having a semicircular cross section which can be filled into the joint with less labor even when the width of the joint is narrowed during the filling work, upon caulking work for a building. Ž<P>SOLUTION: The tool 1 has a plurality of guides 3 corresponding to a cross sectional shape and size of the backup material 2. When the backup material 2 is put into an inlet port, it is cut and divided into an intended size by a blade 5 which is arranged at an outlet port of the guide and is adjusted in the position for obtaining a needed cross section. By making the dimension of a hole of the guide 3 adjustable, the backup material 2 can be cut and divided into any sectional shape and size. For filling the joint or the like, the semicircular backup material 2 can be filled in the joint with less labor than when using the one having a quadrangular cross section even when the width of the joint is narrowed during the filling work, since both ends of the semi-circular backup material are thin.
