Blade set, hair cutting appliance, and related manufacturing method

This invention describes a hair cutting blade set where the stationary blade, which rests against the skin, features a special perforated section. This section is like a foil with many small, round holes arranged in a staggered pattern. A moving blade then works against this perforated stationary blade to cut hairs that poke through the holes.

Why it matters: Advances in precision manufacturing, such as micro-stamping or laser etching, could make the intricate perforated foil and custom blades more cost-effective to produce than in 2022.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPrecision perforated foil, custom blades, tight tolerances
