Saw bits to cut wood bite the wood (so to speak), anciently saws or axes used to split (“bite”) huge logs in two for hollowing-out to make boats (bites of same etymology), like the eight well-preserved ancient boats discovered at Peterborough, England in a dried-up tributary stream of the Nene river which flows into the North Sea, boats up to 28 feet long all carved of long log halves (of oak, alder, or lime), buried in a dried-up tributary of the Nene because they were sunk there (probably ceremonially) when it flowed, during (or shortly after) the Ice Age which ended circa 1500 b. c.
