Round Chain (round tooth round grind):

A round chain is the most common shape. It is the easiest to sharpen; even an average chainsaw user can sharpen this dull chain with a round file. The edge on the round chain tooth is better supported and is larger, which ensures its durability. It’s pretty good at stay-sharp-ability.

Chisel Tooth (square tooth round grind):

Chisel tooth chains have square tooth and round grinds, which enhances their cutting capacity. It can cut up to 15% faster than the round chain. A round file can also sharpen this chain. An average chainsaw user can also maintain this chain well. However, the stay-sharp-ability is not as good as the round chain.

Square Tooth Square Grind:

This chain is sharper than the round and chisel chain. It has about 25% more cutting capacity than the round chain. It can perform cutting tasks incredibly if appropriately maintained. However, it cannot be maintained by an average chainsaw user as it’s pretty professional and heavy-duty. Its stay-sharp-ability is also incredible. You need to have a particular file according to its size to sharpen it.
