Thumbing a saw to test for spring steel

As any of you know if you know me, I can’t get near a saw without thumping on it with my thumb and hearing the tone. A wile back I said I’d make a quick vid of me doing it and I bought a saw this past weekend that was one of the cleanest I’ve heard. I normally bend my hand to raise and lower the pitch but this is so clean I just wanted to play one note and hear how long it would go.

Listen for yourself.

That’s some pretty music to this old man’s ear.

Nice saw too. – Len

I’m not very familiar with handsaw steel. Does doing this reveal the quality of the steel?

There are a few theories behind the ring. Its due to the tension in spring steel and all saws or metal will do it to some degree. One popular reason is if the saw plate were bent the sound wouldn’t be heard all the way through. It would travel to the bend and stop. It also give you an idea of how much tension and spring is left in the plate by the strength of the sound. All this being said I do it because I can, and I see it as the soul of the saw. If I’m gong to take time sharping and refinishing a saw it’s got to have character and soul at the outset.

I was under the impression that this test indicated the tension in the saw plate. I have a Atkins 65 that is my best note player but not nearly as good as this one. I have some very old D8’s that are dead flat (no note/ring ) but saw just fine. So I am still wondering how important is to have a good note player. But I do admit a saw with a nice ring will attract me like a magnet.
