I tried the little 16" 10 point cross cut saw that I have been restoring today, and I was extremely pleased.
For a carpenter that did small odd small carpentry jobs, I could see how it would be very useful in a carpenters tool box, along with a similar sized rip saw. You want to be able to carry a lot of tools to do odd jobs, to be able to face different types of tasks, but don't want to carry a ton of weight. This would have been especially true a century ago in the small types of towns I grew up in, and maybe in a lot of other locations as well.
Back then the carpenter would have had to walk to where the job was every day. He had to carry his tool box to the job, and he didn't want to go back home to get a tool, so his tools had to be flexible and be able to handle many types of tasks. Thus the small odd job carpenter probably wasn't going to carry several 26" to 28" saws, a big jointer plane, and several jack, smoothing, and fore planes. He knew what jobs he was going to do that day, so brought specialized tools he needed, and would have left out others. If he was building a small shed, his bigger saws would have come along, not the 16" saws, but for a lot of jobs the 16" saws would have been just fine.
You can see why Stanley marketed their #6 as a shorter jointer plane. A #4 and a #6 with a couple of different shaped blades, and a Stanley 45 could do lots of different things. An older carpenter friend, of years ago, told me he did a lot of work with a Stanley 45 when building houses when working for his dad 50+ years before I knew him.
At any rate, I can see why a small saw would be useful for such a tradesman.
What do you think, was that why Disston sold the smaller, yet high quality saws?
What tools would you take in your carpenters tool box if you were a small job carpenter a century ago?
