Well a chain saw is designed to cut though wood at a fast pace by taking out larger peices of wood then an average saw. they really dont cut flesh, more or less just rip out chunks of it. They are dangerous in untrained hands.
Obviously a motor powered chainsaw is much more powerful (and dangerous) than a simple handsaw.
A jackhammer is indefinetly loud and keeps going consistently.
He uses a chainsaw, hence Texas chainsaw massacre, but he also uses a machete at some points :in the movie Stan Helsing he uses a leaf blower XD
18 or older and not any age as some where answered before.. You cannot be under the age of 18 to use a chainsaw because it's heavy and dangerous.. However...if you take off the chains and would like to use it for halloween, I would say 15 and higher.
