RAZOR BLADE TECHNOLOGY |
摘要 |
An inter-blade guard of a suitably ductile material for a razor cartridge is provided with an elongated weakened region. The weakened region is provided after the inter-blade guard is attached to a surface of a razor blade. The weakened region is provided by the application of laser energy that forms a groove along a side of the inter-blade guard. The root region of the groove undergoes intergranular carbide precipitation to locally embrittle the intergranular boundary regions in the groove root region of the otherwise ductile material. |
