Blade set for a hair cutting appliance arranged to be moved through hair in a moving direction to cut hair

This invention describes a hair clipper blade set where the stationary blade is made from two parts: a metal piece and a support. The metal piece is shaped to have unique double-walled teeth and is tightly pressed onto the support. A moving blade then slides between these two parts to cut hair, with the claims specifically detailing this force-fitted, double-walled construction.

Why it matters: The core manufacturing challenge of precision metal forming and force-fitting intricate, double-walled blade components remains significant. No specific technological advancements since 2018 have fundamentally simplified this specialized production process.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPrecision metal forming, force-fitting, custom tooling.
