Abstract
The present invention relates to a coated gall-resistant surgical saw blades. One such blade includes longitudinal ribs extending outwardly from the opposed faces thereof which combine to define a total blade thickness greater than the width of the lateral extension of the teeth thereof. The ribs are sized and configured to slidably engage a precision slot in a guide designed to be used to guide the blade in cutting movements. The interaction between the ribs and the slot prevents engagement of the blade teeth with the slot while reducing the surface area of engagement of the blade with the slot to reduce friction. All disclosed blades are coated with a hard, lubricious, metallic, wear resistant coating which is metallurgically bonded to the metallic surface of a respective blade through a coating process forming a part of the present invention.
