PROBLEM TO BE SOLVED: To solve the problems wherein considerably large pushing-up power is required for forming a cut at the lower side of a branch to be pruned by a knife-shaped blade, and when the branch is present at a high position, it is difficult that the cut is formed at a desired position, although a conventional saw for pruning has the knife-shaped blade installed in the lower part of a sharpened saw blade for the purpose of the formation of the cut in the lower part of the branch.SOLUTION: The hand saw is equipped with a circular saw instead of the knife-shaped blade so that the cut may be formed by the circular saw by stroking the circular saw in the front and rear direction while pushing the circular saw against the lower part of the branch. As a result, the cut can be formed accurately at the desired position of the lower side of the branch. Besides, the cut can be readily formed by stroking the blade of the circular saw while pushing the blade against the objective branch, although a considerably large power is required for the formation of the cut by the pushing up. The blade of the circular saw can be attached to the tip part of the saw, the lower part of the saw or the back part of the saw, and a position convenient for a user can be selected.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の剪定用鋸では枝下部に切り込みを入れる目的でナイフ状の刃物を目立てした鋸刃の下部に装着していたが、このナイフ状の刃物にて剪定する枝の下部に切り込みを入れるのは相当の突き上げの力が必要でしかも高所にある枝の場合には希望する位置に切り込みをいれるのが困難であった。【解決手段】本発明ではナイフ状の刃物の代わりに丸鋸刃を装着し、その丸鋸を枝の下部に押し当てて前後にストロークさせ丸鋸刃で切り込みを入れるようにしたものである。これにより枝下部の希望する位置に正しく切り込みを入れることが可能になる。しかも突き上げて切り込みを入れるには相当の力を必要とするが、本発明では目的の枝に丸鋸刃を押し当てて前後にストロークさせることで簡単に切り込みを入れることが出来る。鋸の先端部、または鋸下部、あるいは鋸背部に丸鋸刃を装着可能で使用者の使い勝手の良い位置に丸鋸刃をとりつけることが出来る。【選択図】図1
