According to TURTLE :

Hey tell me about this Rip Chain thing ! Do you use it to split the wood ?

A rip chain is a special chain used for cutting logs lengthwise. Fewer teeth
and ground somewhat differently. It's almost exclusively used by people
with portable chain saw mills slabbing off lumber. These are little more
than a chain saw plus a bar guide.

I don't think too many people split firewood with a rip chain. Way too slow.
A rental hydraulic splitter is MUCH faster.
