Other aspects are very important, Angle, shape, hardness, cutting edge toughness, joint precision, smooth opening and closing, handle design and surface treatment.

其他方面也非常重要：角度，形状，硬度，剪切边的韧性，接合处精密、顺畅的开合，手柄设计和表面处理。

According to the result of right Angle free cutting experiment, the mathematical model of the cutting force for the arc-edge insert is established.

根据直角自由切削的试验结果，建立了圆弧刃刀片切削力数学模型，同时编制了软件进行预测。

Such an Angle is not too sharp in order to allow the use of blades that are not too thin for maintaining a stable quality of the blades at the cutting edge.

这个角度不太锋利是为了使用不太薄的刀片以维持刀锋处稳定质量。
