A swingblade sawmill utilizes a single circular sawblade which pivots about a 90 degree point, to saw in both vertical and horizontal planes. The single blade travels horizontally in one direction down the log, and returns in vertical position, thus removing a sawn piece of timber.

A swing saw is also sometimes called a cut-off trim saw in a mill for cutting right angle to the direction of the wood grain. A swing saw is a very dangerous tool ...
The original powered head saw was composed of long, narrow blades that used an up-and-down motion, a reciprocating saw. Each blade was set at a fixed width meaning each log was cut identically, regardless of flaws. This design was not energy efficient and around 1860 sawmills began to adopt the more efficient circular saw. In the 1870s, the ...
Rip cuts are commonly made with a table saw, but other types of power saws can also be used, including a radial arm saw, band saw, and hand held circular saw.In sawmills the head saw is the first rip-saw a log goes through, which is sometimes a gang-saw, and then the cants may be resawn using other saws and then edged in an edger and sometimes cut to length by a crosscut saw.
