For Ash's chainsaw hand, effects artist Verne Hyde modified a real chainsaw, replacing its gasoline engine with a small, 12-volt electric motor, leaving space for Campbell to insert his hand into the body of the saw. The teeth of the saw were filed down for safety purposes, and tobacco smoke was pumped through a plastic tube that ran up Campbell's leg to simulate chainsaw smoke.
