PROBLEM TO BE SOLVED: To provide a cutting tool that can efficiently cut weeds growing in the gap between structures of constructions of concrete, etc.SOLUTION: A cutting tool 11 is constituted of a shaft part 17, a shank 9 integrally provided at the rear end of this shaft part 17, and a blade part 19 integrally provided at the tip of the shaft part 17. The blade part 19 is formed in a wide shape of a thin wall. The blade part 19 is constituted so as to gradually become thin toward the tip and have a cutting blade 21 at the tip. The back side 23 of the blade part 19 is flatly formed to obliquely extend in a surface side to a shaft direction of the shaft part 17 from the rear end toward the tip. The surface 25 of the blade part 19 is flatly formed to obliquely extend in the surface side to the shaft direction of the shaft part 17 from the rear end toward the tip.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】コンクリート等の構造物の構成体同士の間の隙間に生えた雑草類を効率よく切断できる切断工具を提供する。【解決手段】切断工具１１を、軸部１７と、この軸部１７の後端に一体的に設けたシャンク部９と、軸部１７の先端に一体的に設けた刃部１９と、から構成し、刃部１９を薄肉の幅広状に形成する。刃部１９を、先端に向かって漸次厚さが薄くなり、先端に切断刃２１を有するように構成し、刃部１９の裏面２３を、後端から先端に向かって軸部１７の軸方向に対して表側に傾斜して延びる平面状に形成し、刃部１９の表面２５を、後端から先端に向かって軸部１７の軸方向に対して表側に傾斜して延びる平面状に形成する。【選択図】図２
