摘要： A blade is described. This blade includes a substrate having two surfaces that meet at a cutting edge of the blade. At a given location along a length of the cutting edge, the two surfaces are at an angle with respect to one another. Moreover, angles between the two surfaces are different at at least two locations along the length of the blade. In particular, the angles between the two surfaces may vary along the length of the blade. Furthermore, the blade may include islands having top surfaces positioned at other locations along the length of the blade. These islands may protrude above the cutting edge to protect skin of a user when the blade is used to cut hair. In addition, the islands may include fluidic channels that provide a fluid (such as air or a lubricant) at the top surfaces of the islands when the blade is used.
摘要翻译： 描述了一个刀片。 该叶片包括具有在叶片的切割边缘处相交的两个表面的基底。 在沿着切割边缘的长度的给定位置处，两个表面相对于彼此成一角度。 此外，两个表面之间的角度在沿刀片长度的至少两个位置处是不同的。 特别地，两个表面之间的角度可以沿着叶片的长度而变化。 此外，叶片可以包括具有位于叶片长度的其它位置处的顶表面的岛。 这些岛可以突出在切割边缘上方，以在刀片用于切割头发时保护使用者的皮肤。 此外，岛可以包括当使用叶片时在岛的顶表面处提供流体（例如空气或润滑剂）的流体通道。
