Blade set, hair cutting appliance, and related manufacturing method

This invention details a method for manufacturing the blade set of a hair cutting appliance. It describes a stationary blade with two distinct wall sections that create a guide slot for a movable blade, with the wall sections joining to form the tips of the teeth. The method also specifies how the movable blade fits into this slot, guided by a central part of the stationary blade.

Why it matters: Since 2020, advancements in precision manufacturing, particularly metal additive manufacturing, have made creating intricate metal geometries like these blade components more feasible and cost-effective. This could simplify the production of the described complex blade structure.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePrecision metal forming for intricate blade geometry.
