Historical Examples of circular saw
Many kinds of work, however, can be done only on the circular-saw.
After this the block is taken to a circular-saw, which cuts off the corners, and reduces it to the form of an octagon.
In this way, it is possible to cut very large logs with the circular-saw and with less waste.
The circular-saw is not a perfectly flat disc, but when at rest is slightly convex on one side and concave on the other.
