Chainsaws — the ultimate tool for some, the ultimate nightmare for others. Chainsaws are actually neither. Once considered the primary tool of professional loggers, ranchers and farmers, chainsaws became a popular homeowner tool when Robert McCulloch introduced the first lightweight model back in the late '60s. Since that time chainsaws have become increasingly popular with homeowners. Of course, they're also used by numerous professionals, such as arborists and loggers.

Chainsaws can be used around the house for tree pruning, storm cleanup, cutting firewood, felling trees and even creating rough carpentry projects such as fences, fence posts and others. Chainsaws are available with a wide variety of bar lengths and engine power, including electric- and gasoline-powered models.

Before choosing a chainsaw, first consider the uses you will need it for. Will the saw be used primarily for trimming, felling, cutting or all of those chores? Also ask how often the saw will be used — regularly, occasionally or extensively

.The saws are basically available in three sizes: mini, mid- and heavy-duty. The mini's, also called light-duty, range from 30 to 40cc with bar lengths ranging from 12 to 14 inches. Midsize chainsaws range from 40 to 60cc with bar lengths from 16 to 24 inches. Professional, or heavy-duty, saws range from 60 up to 120cc and can have longer bars than most homeowners can fathom. And it requires some muscles to use them.

For the most part you should select the saw based not only on engine size, but the diameter of wood you would most often be cutting. With proper use, you can safely cut logs with diameters almost double the length of the bar
