A method of modifying a cutter link (240) of cutting chain for a chainsaw may include forming the cutter link (240) to include a base portion (280) and a cutting portion (270) extending away from the base portion (280). The cutting portion (270) may include a side plate (300) and a top plate (310). The top plate (310) may include a top face (316) and a bottom face (314). The side plate (300) may include an outer face and an inside face (304). The method may further include determining a maximum non-homogeneous material hardness expected to be encountered during cutting operations, selecting a coating material having a hardness at least 1.3 times the maximum non-homogeneous material hardness, and coating a treated surface of the top plate (310) and/or the side plate (300).
