Abstract: A shear blade assembly (10) on, for example, a tree harvester (12) has first and second blade portions (14,16)which are urged into opposite portions of a tree circumference to cut the tree. A desirable shape of the blade assembly (10) is a concave configuration which minimizes tree damage and efficiently distributes loads through the shear blade assembly (10). An improved method for making the concave shear blade assembly (10) includes cutting blade surfaces (42,44) on a blank (30) and leaving a web (50) between the surfaces (42,44), then depressing the blank (30) to form the desired shape and dividing the blank (30) along the web (50) to form the first and second blade portions (14,16). Making the surfaces (42,44) before shaping and dividing the blade portions (14,16) overcomes problems stemming from distortion of blades which are cut along a curvature following the step of obtaining the desired shape in the blade assembly (10).
