Abstract
A method of manufacturing a bedknife for a reel cutting unit comprises providing a base having a tool steel insert that forms a cutting edge of the bedknife. The base comprises a heat treatable steel. Both the base and the insert are heat treated prior to joining the insert to the base. The insert is then integrally joined to the base by brazing the two together using a silver based filler between the two.
