Abstract

一种菜刀，由刀柄和刀体组成，刀体的后部向内凹进去，以便于手可方便的握住刀柄，刀柄向前延伸至刀体的中部。本菜刀刀体后部凹进和刀柄向前延伸，消除使用时支点与力点两条垂线之间的距离。其优点为：一是省力。手臂发出的力量沿垂直方向通过菜刀直接作用于物体，不再浪费体力。二是舒适。握刀手不需要克服扭力，手腕不易疲劳。

Description

菜刀
技术领域
 本实用新型涉及一种菜刀。
背景技术
使用普通菜刀切割物体时，握刀的手必须朝两个相反的方向用力。一是朝下前方用力，为了切开物体；二是朝上后方用力，为了保持刀刃与砧板的平行。时间一长，手腕就会感觉疲劳酸痛。切割未经冻结的肉类等硬度较大的物体，这种现象就更明显了。
发明内容
实用新型的目的是提供一种用力更加合理、省力的菜刀。
本菜刀由刀柄和刀体组成，刀体的后部向内凹进去，以便于手可方便的握住刀柄，刀柄向前延伸至刀体的中部。
本菜刀刀体后部凹进和刀柄向前延伸，消除使用时支点与力点两条垂线之间的距离。其优点为：一是省力。手臂发出的力量沿垂直方向通过菜刀直接作用于物体，不在浪费体力。二是舒适。握刀手不需要克服扭力，手腕不易疲劳。
附图说明
图1为本实用新型菜刀的整体结构示意图。
具体实施方式
本菜刀由刀柄1和刀体2组成，刀体2的后部向内凹进去，以便于手可方便的握住刀柄1，刀柄1向前延伸至刀体2的中部。
