A rotary cutter head for attachment to the driven shaft of a motorized hand supported apparatus for cutting vegetation, said cutter head comprising,
- a flexible metal cutters each of hook shaped configuration at one end and having a substantially straight exposed cutting segment at its opposite end,
- a circular body removably coupled to said shaft, said body including a central boss and radially offset abutments constituting cutter retention means engaging each of said cutters at spaced apart points therealong so as to permit flexure of the cutter along its length to minimize cutter breakage,
- said cutters in partial overlying relationship with one another,
- a closure plate for attachment to said main body, and
- a retainer engageable with said body for closure plate retention.
A flexible metal cutter of generally bowed configuration for installation within a rotary cutter head of a vegetation cutting tool having multiple spaced apart abutments thereon and a central boss, said cutter having spaced apart end segments adapted to abut multiple cutter head abutments, one of said segments being of hook shaped configuration for permanent abutment with one of the cutter head abutments, the remaining end segment being substantially straight and in spring biased contact with a remaining abutment.
