Popular fiction has shown us the awesome, brutal power of the chainsaw. Its lightning-quick, rotating teeth can easily slice through flesh and bone, making the strength and skill required for manual weapons unnecessary. Its roar might also give the owner a much-needed psychological boost—empowerment in a situation where abject terror is a given. How many horror movies have you seen in which this industrial killing machine has spelled doom for anyone and anything it touched? In reality, however, chainsaws and similar powered devices rank extremely low on the list of practical zombie-killing weapons.
