    • An elongated flat strip of martensitic satinless steel material for use in manufacturing razor blades is provided with an elongated weakened portion. The weakened portion is provided after hardening, sharpening and cutting edge coating processes are performed. The weakened portion is provided by the application of laser energy that forms a groove along a side of the razor blade and converts previously tempered martensite to untempered martensite at the weakened portion. The razor blade is attached to a support and removed at the weakened portion. The weakened portion can be provided before or after the razor blade is attached to the support.
    • 用于制造剃刀刀片的细长马氏体无玷污钢材带设有细长的弱化部分。 在硬化之后提供弱化部分,执行锐化和切边涂覆工艺。 弱化部分通过施加激光能量而提供,该激光能量沿着剃刀刀片的一侧形成凹槽并且将先前回火的马氏体转变为弱化部分处的未回火的马氏体。 剃刀刀片连接到支撑件并在弱化部分处移除。 弱化部分可以在剃刀刀片附接到支撑件之前或之后提供。
