Jaw saw.

Max cutting diameter is 4" - cost is $130 to $160 depending where you look and if corded or battery. Amazon says battery version is frequently returned item...

Seems like a narrow niche product and the reviews are quite unkind...

I'm guessing the target market is folks who need a small chainsaw for pruning but are terrified of the conventional design with its exposed, unguarded blade. For about the same amount of money, Harbor Freight will sell you a cordless, 10 inch chainsaw of conventional design...

I suspect the conventional design would be much more utilitarian. (Although, I wouldn't lend it to many of my neighbors, the ones who can't figure out what hammer to use to drive screws into wood.)
