Blade set, hair cutting appliance, and related manufacturing method

This invention describes a stationary blade for hair clippers or shavers. It's uniquely made from a combination of metal and plastic, where the metal forms the skin-facing part. The blade features two distinct wall sections that create a precise slot to guide a moving cutter blade, with these walls also forming the cutting teeth.

Why it matters: Advances in precision injection molding and composite material integration since 2020 could now make the complex integral formation of this blade more feasible for cost-effective mass production.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
