  • Saw blade for parting cuts made in an oscillating or rotary manner
    Patent number: 5569257
    Abstract: The saw blade has a non-cutting blade area (2), whose thickness D is smaller than the width of cut S of its cutting area (4). The non-cutting blade area (2) has on either side a thin surface coating (11) of a relatively soft and biologically neutral precious metal. This leads to much better cutting characteristics and to reduced friction. The saw blade is particularly suitable for bone surgery.
