This invention relates to a curved saw, the saw body 1 is curved from the base toward the tip. The concavely arch-shaped side rim of the curved saw body 1 is provided with many saw teeth 2. The cross angle ([alpha]) of a cutting edge 3 as the base side rim of the saw tooth 2 situated at the base of the saw body 1 with a tooth point line 5 joining the tooth points 4 of the saw teeth 2 each other is made larger, while the cross angle ([alpha]) of the cutting edge 3 as the base side rim of the saw tooth 2 situated at the tip of the saw body 1 with a tooth point line 5 joining the tooth points 4 of the saw teeth 2 each other is made smaller. Thereby, the total saw teeth from the base to the tip of the saw body can be utilized, realizing the objective saw, mainly a pruning saw, enabling cutting works to be smoothly performed with a constant force.
