ABSTRACT:
The invention provides a saw chain comprising connecting links made of relatively inexpensive nonhardened metal and saw tooth links made of an extremely hard material, such as carbide, which maintains the sharpness of the saw tooth links despite prolonged use. The connecting links are pivotally secured through registering apertures in the links. In one form of the invention the pivot pin is separable into a female portion and a male portion to permit the replacement of individual saw tooth links on the saw chain.
