It's about 9" long. It has no marks of any kind. It has two thumb screws. The red part has some kind of a blade with teeth that can be replaced. Maybe picture four will help.
I have no idea what this is. | ||

Looks like a part of some kind of lockdown device???
The right side should unscrew to open the clamp, then put a pipe in the clamp and screw it shut. The cutter teeth are blurry in the picture but they appear to be for cutting threads in the end of the pipe. This type tool would have been used before tap and die sets were invented. I believe Armstrong tool company made one similar in design to this.
I don't see a way this can thread pipe. Blade looks more for scribing/scoring something.
Kinda agreeing w/bb2. Though its 'non handle' end does look like its made to clamp onto a pipe (or something slender and round anyway?) if it was a thread cutter there'd probably also need to be some sort of rotational motion to it too (instead of what appears to only be a back-forth 'hinge/axle' arrangement) which I'm not seeing, as well as a probably more robust method (than the spring) to actually get its blade to do much of any cutting.
I could imagine it might do some sort of "lengthwise" cutting/scribing operation to something instead, but I surely don't know what/why...maybe large electrical cables??
What a curious thing anyways Jimmyjet, and welcome to CW too, BTW...?! :-)
I don't see how you could make threads with it if the pipe is clamped down but I could be wrong. Thanks everyone for your comments.
As I said in my original post the photo of the cutter is blurry. As for the rotation of the pipe, it would be turned by a bridgeport or screw machine. The clamp would not be entirely tightened allowing the pipe to spin while being held in position.
In that I can't see the cutter, I will post a link to a modern replacement cutter and perhaps someone with better eyes can compare the design to the one posted above.

Fhr, those are an entirely diff. thing for a lathe. The blade on this is obviously thin like a hacksaw blade & not for cutting threads.
Thanks BB2, I can't make out this cutter clearly. Not sure if it is the picture or old eyes.
If I could figure out how to put another picture on I would show a better one. The cutter has small teeth about the size of an exacto saw and is a little thinner than a hacksaw blade. Thanks for the input.
You still have one more pic available to add to this showing Jimmyjet --just hit the <edit post> button which will take you back to a screen where you can add it in exactly the same way you did with the first three. Then hit <save>... ;-) :-) :-) :-)
I believe this tool has been discussed before here. It is used to cut flexible metal electrical conduit known as Greenfield. No or Not ?
