It cuts faster than the old style. This chain has only a couple of test cuts (in regular wood) As you can see the gold finish is still on the cutters.Shipping - $5.25 to USA and $24.75 to australia, canada, or new zealand that is what usps charges for international small flat rate boxMore on on the chain from stihl...With standard-sized cutters, the RD3 is extremely durable and produces very good results in all types of wood. It is especially suited for cutting dirty wood, treated wood, roots and hardwoods, which would quickly dull conventional chains. This chain must be re-sharpened with a formed diamond grinding wheel.
