Abstract

A method of making a knife blade (10) having a zig-zag cutting edge (16) with sharp V-shaped apices (A) on at least one side, including the steps of taking a metal plate, forming said plate with a plurality of parallel corrugations (11) which extend from an edge thereof, each corrugation having a V-shaped apex, the forming operation including displacing metal at each apex into a region (20) outwardly of an arc of radius not less than the thickness of the plate in regions spaced from the associated apex and having a centre of curvature lying on a bisector of the apex.
