Chainsaw (IndustrialCraft 2)

The Chainsaw is an electric unbreakable tool used as a replacement for an axe, shears, and a sword. It needs EU to work and can be charged by placing it in a Generator, BatBox, MFE, or MFSU that has stored power or by wearing a charged BatPack, RE-Battery or any other wearable EU storage item. It can store up to 10,000 EU. Each shear or block break takes 50 EU, giving the Chainsaw a total of 200 uses before needing a recharge, however when hitting mobs it deals 10 damage (5 hearts) at 100 EU per hit, giving it only 100 uses before needing to be recharged. It can be upgraded to an Advanced Chainsaw.

To shear sheep with the chainsaw, simply right-click the sheep while holding it.

The Chainsaw, through the use of enchanted books and anvils, can be enchanted with Efficiency.
