A total waste of money. Spit is the best lubricant. Just lick your saw
blades. Never fails. I've been doing it for more than 30 years.

And after the first few years, either you learn to lick the blade in the
downward direction, or the cuts stop hurting so much in any case.

personally, I prefer bur life over spit, especially on drill bits. Seems less
messy. Not that it works better, though...

On drill bits, I use Wintergreen oil.


one "tongue-in-cheek" problem with spit, of course, is that it might cause a
blade to rust.

Rust has never been a problem, since the blades do not stay wet long
enough. Thew spit evaporates due to the heat developed through
friction. That's how fast I saw. And when I file, it gets so hot,
sparks fly!

That might mean needing to change the blade more than once a
year or so, before the teeth are totally worn off.

Most of the time, my blades do indeed wear out and get dull, before they
break. It was very different when I was a beginner.
