Weird tool identification "HELP"

[Mustangfe]

Howdy folks, I'm really stumped here. I've tried google image search, bing image and a few others.. There are no marking on the tool at all (at least that I could find). Any help on intended purpose would be much appreciated.

Thanks

You will talk!

Have no idea but looks to me like it could be used to mark a cut line on a pipe, etc. Maybe vintage muffler tool? IDK.

The teeth on the "cogs" are not pointing in the same direction. It seems therefore that it is designed to grip something rather than to rotate around something.

My thought was lab ware based on (appearance of) light weight, but the knurling on the end of the handles says those are grips.

dunno the size, but what about a cardboard storage tube cutter . think carpet rolls etc

PVC cutter?

Pipe decapitator.

Pipe decapitator.

It sort of looked medical, but on closer inspection the wheels aren't right.

So I've taken it apart, it's all steel, the "cutters" are mounted on spring loaded bolts, assuming so they can spin/rotate. As mentioned, they are/were in opposite orientation. Considering both sides of both handles are knurled, and the twin sliding posts, it seems designed to be used with two hands. I was kinda thinking a pvc cutter, wire insulation cutter, or holder of some sort, maybe even a type of oil filter wrench. But since the wheels can spin, maybe a debarking tool? Knurl tool for wood? Still stumped...

Perhaps for cutting something circular when there isn't enough space to use a saw but there's plenty of room to swing the handles around.

I've figured it out, it's a Hastings piston ring groove cleaner from the '50s-'60s.

Congratulations you stumped us.

How'd you figure it out?

I'm guessing this video, unless that chap is the OP?

Would be pretty hard on ally pistons .....might be for cast iron pistons that used to get really hard carbon deposits in the grooves

Ah I was trying to find this thread last night as I saw that youtube video suggestion!

Thumbed through thousands of pages of old tool catalogs, lol. I had an idea that it was a groove cleaner, just took a while to find it. Archive.org is a great website for old tools.

Knurlung was a first guess, but no way it would work. Debarker, maybe. Annoyance, absolutely.
Using this to clean pistons? Not even Detroit
