The small capacity Chainsaw is the most basic of all the Chainsaws, and as such isnt as powerful as either. The large capacity has double the run time while the improved kills faster. This one is not bad by any means but upgrade when possible. The chainsaw is a close range killer. It needs fuel to operate but when working, this thing can kill lots of zombies and is best for crowd control against swarms. This thing works even against armored zombies. A good trick for this Chainsaw is to fill bottles with fuel to keep it going or longer since if you have three fuel bottles, you basically have a large capacity chainsaw because to only advantage is more fuel.

If possible, uncraft and recraft the chainsaw to a improved or large one.

If you have the storm warning edition and have nina, craft the flamethrower if possible
