What is a tank saw?

	The miter saw is essentially an earlier version of the bow saw. It has a long blade with large teeth in a wooden frame. However, unlike the bow saw, it has an H-shaped frame rather than a curved one. While the angle grinder was designed for smaller spaces, the circular saw was designed for larger projects. Even though the circular saw has been around for centuries, it's unlikely you'll find one on a shelf at your local DIY store.
	Почему нет? The hacksaw has largely been replaced by the bow saw, which does the same job but is generally considered easier to use and generally less expensive. A bow saw has a hollow steel frame that is often much lighter than a solid wood saw.
	The bow design is also seen by some as being more compact compared to the H-frame on saws. However, the front saw is still in use, especially in North America, and many people make their own from wire and old bits of kindling.
Why is it called a saw?
	The term "bucking" was used to refer to the rough sawing of logs ready for use as firewood, for which a saw saw is specifically designed.
