The overwhelming number of handsaws that we see in the wild are 26" long and made by legendary companies like Disston, Alkins, or Simonds. There were many other companies making handsaws, but these were the Big Three. And they all made very good saws. Of course, a restored beat-up 50 year old saw probably won't be as nice to use as a never-touched classic saw, but overall the historical choices of steel, tooth pattern and handle design were excellent. These saws were made by people who knew what they were doing, feeding a market that know what it wanted.
Or did they?
In the late 19th century, Warren Bundy of Minnesota City patented a B.M.T. saw tooth design which was put into manufacture by the Montague-Woodrough Saw Co. The BMT's basic concept was miniaturizing the specific design features that made fast-cutting timber saws so compelling - deep gullets and specialized raker and cutting teeth - and modifying them in smaller back saws and handsaws for use in carpentry. This resulted in a kick-ass, fast-cutting saw that blew through material. The execution wasn't free of complications. The BMT saw cut fast but left a marginally coarser surface than did a fine handsaw. The tooth pattern was irregular and could not be sharpened in mechanical sharpening machines like a Foley Saw sharpener. And Montague-Woodrough Saw Co. was tiny compared to the Big Three, making it a challenge to get the saws into distribution.
So the saw design died on the vine.
But let's give a fresh look at these problems. The distribution issue was a fact of 19th century sales and marketing. In order for the saw to be popular, it really needed a big company behind it and it didn't have one. Nowadays the current saw market is a specialty market, and manufacturers of all sizes can get access to customers in all sorts of ways. The marginally coarser surface turns out, upon further examination, to not be a big deal. In general, the main use of any handsaw nowadays is to break down stock so the final edges and ends can be shot for accuracy and the surfaces planed. For regular framing the cut quality is more than very good with little or no splintering out.
The most important reason the saw never caught on, in my opinion: Sharpening! Hand sharpening the saw isn't particularly hard. In many respects, it's easier than sharpening a traditional pattern saw. The company saw fit to include sharpening instructions etched into the side of the saw. A customer could use regular saw files, but the saw couldn't be sharpened in a machine. So on a construction site where all the sharpening services used filing machines sharpening, a BMT pattern saw would be a big deal. Not so today. A computer controlled setter makes setting the saw straightforward work. The saw's pattern of teeth is a little confusing, but hand filing is routine. The BMT is actually a pretty easy saw to sharpen.
At the first Handworks show in 2013, the late Carl Bilderback, gentleman and saw expert extraordinaire, brought a BMT pattern backsaw by Montague-Woodrough Saw Co. and showed it around. Timothy Corbett, TFWW's designer, was working the show with me and was very intrigued. He was working on a knotty problem. We had said for years and years that we would not manufacture a panel saw unless we could make something better than Disston did in the 1920's. We experimented with taper grinding, tensioning, etc. We could make a good panel saw but nothing really better than Disston. I don't feel bad about that: Disstons in good shape are really good. We thought there might be an interesting market for a "hardware store saw" - you know the kind of saw you put in your tool box, take to a jobs site, to a lumberyard, and so on. The blade was only 16" long, which I though was too short for regular work, but otherwise it made sense. The saw's design had a few cool tricks - using a handle that turned it into a square and ruler was also pretty fun - that made the saw especially useful. In our eyes, the big competition was the cheapo saws you get at the big box stores for a few bucks. The handles are crude and uncomfortable, and the teeth can't be resharpened, but they crosscut like a demon. And rip horribly. We thought there might be a market for a nice saw that could rip and crosscut well. But what would be the tooth pattern? The basic rip and crosscut patterns that Disston and others used are fine and dandy, but they don't crosscut as fast as a big box saw (especially in a shorter length). This is where Tim was when we arrived at Handworks. Carl's saw got him thinking.
The actual tooth pattern we ended up using on the hardware store saw isn't a BMT pattern. It's a variant Tim came up with that works a little better, and needs almost no set. We send a prototype to Carl for his comments, and showed the final design to Carl at the 2015 Handworks. He was really pleased that his work and research was able to inform modern toolmakers. The Montague-Woodrough Saw Co in the pictures was a gift from Carl to Tim.
But getting back to our original point. We find in the shop we have a tendency to grab a hardware store saw for all sorts of stuff. I had thought it would be too short for "serious work" but I have to say I was wrong. As you can see in the video below, it cuts fast, doesn't splinter, rips and crosscuts very well, and is just convenient. I just didn't feel the need to go into my toolbox ( a good ten feet away) to get my regular full sized saws anymore. The extra features of the built-in square and ruler have come in handy, but the shorter length means it's easier to store, transport, etc. I don't feel I am going too slow and need a longer saw. Of course a longer saw in the same pattern might be nice, but it would be inconvenient, and I am debating if my two full sized saws that are mounting in the lid of my toolbox should be replaced with one hardware store saw freeing up space for a sash saw.
I don't have a way of predicting certain how popular this type of saw tooth would have become if it had been marketed by a bigger company and was easier to machine sharpen using a 19th century technology, but I think it would have had a much bigger, well deserved impact. I can certainly celebrate it today.
