Before Bandsaws there were Circular Saws

The ability of the Union Lumber Company mill here in Fort Bragg  to cut very large logs was due to the introduction of a Band-saw in place of a circular saw. The circular saws were very  wasteful because of their thickness. You can see a circular saw in operation at Sturgeon’s Mill at Green Hill road in Sebastopol, CA.

Some of the blades were very large to handle the huge tree trunks:

The circular sawbades’ replacement was a band saw blade. This pic shows one similar to those used in the Union Lumber Company.

Now suppose you were building an Egyptian monument (pyramid?) 5,000 years ago. Is this how they cut those blocks of granite? A giant circular saw with a copper blade
