A saw blade contains a body, in particular of a hard material, having a cutting portion. The cutting portion has a length and a width and being provided along its length with a plurality of teeth which are formed by a plurality of grooves. Each tooth being formed by at least two grooves. There is a first plurality of grooves, the grooves of which are parallel to each other along a first direction and in that there is a second plurality of grooves, the grooves of which are parallel to each other in a second direction. The first direction and the second direction are inclined to each other such that along the length of the cutting portion at least one of the grooves of the first plurality of grooves is intersected by a groove of the second plurality of grooves.

A method of manufacturing an agricultural tillage disk blade includes providing a substantially circular-shaped disk body with an outer peripheral edge and a central opening that defines a rotation axis, the outer body being disposed within a first plane. A plurality of waves is formed in a predetermined pattern in the outer peripheral edge of the disk body, and the outer peripheral edge is sharpened to form a plurality of teeth such that at least a portion of the sharpened outer peripheral edge is disposed within a second plane that is parallel to the first plane and substantially perpendicular to the rotation axis. The method also includes machining a plurality of relief portions in each of the plurality of waves at a location radially inward of the plurality of teeth, and heat treating the disk body after the sharpening and machining steps.

A method (100) of producing toothed blades from a strip material (200, 250) is disclosed. The method (100) comprises: cutting the strip material using combined laser cutting (102a) and mechanical machining (104a) or using waterjet cutting (102b) to form a plurality of teeth in an edge of the strip material (200, 250), wherein the cutting is controlled to cut each of the teeth using a flexible programmable geometry. A toothed blade production line (300, 400) arranged to produce toothed blades from a strip material using the method is also disclosed.
