本新型關於一種裁切工具，特別關於一種容易施力的曲線剪刀。The present invention relates to a cutting tool, in particular to a kind of curve scissors which are easy to apply force.

剪刀，主要為一種裁切工具，其主要包含互相樞接的兩刀體，以及分別連結於該兩刀體尾端的兩柄部，使用者操作該兩柄部，以控制該兩刀體相對開閉，而對物件進行裁切或修整。Scissors are mainly a cutting tool, which mainly includes two knife bodies pivotally connected to each other, and two handles respectively connected to the tail ends of the two knife bodies. The user operates the two handles to control the relative opening and closing of the two knife bodies to cut or trim objects.

然而，現有的剪刀在使用時，往往由於兩刀體的刃部皆呈直線延伸，因此，如果利用兩刀體的刀刃末端進行剪裁時，往往會因為相對兩刀體的刀刃之間的開口角度過小，而比較難施力。However, when the existing scissors are used, the blades of the two blades extend in a straight line. Therefore, when cutting with the ends of the blades of the two blades, it is often difficult to apply force because the opening angle between the blades of the two blades is too small.
