A chainsaw (or chain saw) is a portable mechanical, motorized saw. It is used in logging activities such as felling, limbing, and bucking; by tree surgeons to fell trees and remove branches and foliage; to fell snags and assist in cutting firebreaks in wildland fire suppression, and to harvest firewood. Chainsaws with specially designed bar and chain combinations have been developed as tools for use in chainsaw art.
