A chainsaw (or chain saw) is a portable handheld <a href="/facts/Power_saw/mh8PG7xy">power</a> <a href="/facts/Saw/ERUfjrwU">saw</a> that cuts with a set of teeth attached to a rotating <a href="/facts/Chain/KlYIprGC">chain</a> driven along a guide bar.
Modern chainsaws are typically gasoline or electric and are used in activities such as tree <a href="/facts/Felling/eFHrzu3R">felling</a>, <a href="/facts/Limbing/dD0VH6gH">limbing</a>, <a href="/facts/Log_bucking/1Lse1zul">bucking</a>, <a href="/facts/Pruning/7Tbb04v8">pruning</a>, cutting <a href="/facts/Firebreak/RWy2E0U2">firebreaks</a> in <a href="/facts/Wildland_fire_suppression/nKJHnMF2">wildland fire suppression</a>, harvesting of <a href="/facts/Wood_fuel/S6W7k5Pv">firewood</a>, for use in <a href="/facts/Chainsaw_carving/tNYfsnpC">chainsaw art</a> and <a href="/facts/Chainsaw_mill/hlvVNbl8">chainsaw mills</a>, for cutting concrete, and cutting ice.
