A chainsaw is a portable saw that can be powered by gasoline, electricity, or batteries. It has a set of teeth that are attached to a rotating chain, and the chain is driven along a guide bar. Tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, and the collection of firewood are all examples of activities that require its utilization. As a tool for use in chainsaw art and chainsaw mills, chainsaws with specially designed bar-and-chain combinations have been developed. These saws can be purchased online. Concrete is typically cut with specialized chainsaws during the development of new construction projects. When creating ice sculptures or going swimming in the winter in Finland, chainsaws are sometimes used to cut through the ice.
