Mystery Crimper???

[onething]

Found this in my Grandfather's tool box while cleaning out my recently deceased Dad's shop.
We have no clue what it was made to do beyond crimping???

Sorry about the fuzzy last photo - autofocus and one-handed photography

Looks like a saw set for resetting the angle on saw teeth after you sharpen them down a bit.

I've gotta ask, how would you get the teeth in there to set them?

None of the photos show it clearly, but the two anvil supports are arched to form an opening at the bottom. You can see it a little in the second and third images. It fits over the tooth, anvil on the far side, plunger/hammer on the near side. The anvil is usually facetted with different angles to set the teeth at the desired angle, but this one doesn't seem to have that feature. Maybe it adjusts in a different manner.

I still don't see it. Isn't the hammer pointed in the wrong direction (perpendicular to the tooth) or do we assume it rotates?

The knob moves the anvil in or out which controls the amount the tooth is bent over.

Okay. Maybe a jamnut or something to keep the adjustment from drifting once it's dialed in?
This shows how it's used:

The plunger has a triangular footprint that pushes the tooth against the anvil. Usually every other tooth is set one way, then the alternate teeth are set the other. Same principle for circular blades.
However, power saws have really taken over in general use, and their circular blades are either so cheap they're more cost effective to replace rather than sharpen, or the tooth material is so hard and long-wearing that it requires specialized expertise.
