  • Patent number: 4711076
    Abstract: An improved cutting blade structure and method of use is disclosed, characterized by use of a flexible, planar member formed of a plurality of interconnected elongate tubular segments which when rotated, contacts and effectively cuts vegetation. Due to its planar tubular segment construction, the cutting blade constantly exposes a multiplicity of new cutting edge surfaces during use and possesses an extremely low mass which reduces the possibility of personal injury to a user or property damage to structures located in the vicinity of use.
