Dragsaw

Early dragsaws of the modern era were powered by levers or foot pedals,[2] steam and later gasoline-powered.

The post-modern steam-powered dragsaw was most commonly used in logging industry rather than merely clearing land due to its versatility.

Many of the basic design principles from early dragsaws still apply to current products in the industry today.

The inventor Robert G. Moores hypothesized that early non-mechanical versions of dragsaws may have been used to cut stone in the Fourth Dynasty, Egypt, with copper saws suspended from ropes and advancing into the stone blocks by gravity.

Dragsaws powered by humans would often stem from a lever the person would use to manipulate the saw blade in a much easier manner.
