Just picked up three saws, at least two of them are Atkins -- not at a bargain basement price, but reasonable enough that I'm happy, even though two of them are probably rather unremarkable. (I have a fondness for Atkins saws because they were made in Indianapolis, where I live.) One is a "Five Hundred" model with a stainless steel blade. According to the etching, it was made when Atkins was a division of Borg Warner, the namesake of the trophy given to the winner of the Indianapolis 500, which I assume explains the name. The other relatively ordinary saw is a No. 401.
The third saw is the real reason I bought them. . . an old floor saw . . . maybe an Atkins or maybe a Warranted Superior -- I'm not sure yet. It has a Warranted Superior medallion, but the handle looks like an Atkins. As I understand it, Atkins came up with its flooring saw design, then Disston and others followed suit. Although I think this design was a clever solution to the problem of cutting through an existing floor, I can't think of a single thing I'd ever use it for. I'll probably clean this one up and hang it on the wall just because it looks so cool.
