Some type of tin cutter???
« on: July 21, 2015, 07:20:43 PM »
My great uncle had this in his shop. I'm not sure what its purpose is. I'm thinking it cuts slots in tin. Your help is appreciated. Thanks.

Looks kinda like a stove pipe crimper but I have never seen another one like it?

don't look like it can cut?
the step teeth going the wrong way for a stove pipe crimper.
might be a crimper for banding / strap iron?

I also was thinking steel banding sleeve crimper.

the grooves would make the sleeve harder to slide loose.

I don't think it's for cutting either.

My best guess would be some sort of crimping tool.

Thanks for the replies everyone. The reason I think it's for cutting is the teeth move all the way through that opening.

What are the general dimensions, and what's the clearance on the side of the blade to the socket as the tool is closed?

I believe it is a medical instrument for cutting plaster casts.http://www.medezine.co.uk/product-range/stille-cast-shear/

Sorry it took so long to get back to you. Thanks again everyone. I would say it's roughly 2 feet long and there is no clearance.  No, I have not tried cutting any sheet metal. WOW! That cast cutting tool has to be it. It's identical.  I have no idea why that would be in his shop. LOL!

Just bumping the post again. This is not a cast cutting tool. Even though it looks identical. I have noticed upon closer review of the pictures of the cast cutting tool that it has more of a blade jaw. This tool looks more like it punches these slots out of it. Any more thoughts?

bigslicktux, I still think it is a plaster cutter. Finish and style definitely put in the medical instrument field, this type of cutter has probably been made for a 100 plus years by a large number of medical instrument makers so exact details and ideas would have varied greatly. I have very large number of trade tool catalogues and nothing like your tool is to be found in them.  Here is a scan from the ONE medical catalogue that I have!?

I for one am convinced by the medical interpretation. It is clearly a 'nibbler' of some kind, and the teeth suggest that it is designed to nibble through something crunchy and friable (like plaster) rather than something that cuts cleanly (like sheet metal).  I do find myself wishing I had more medical device catalogs, however: I've desired them ever since I had to catalog a set of Civil-War-era surgical instruments 20 years ago, but they tend to be quite pricey. GoogleBooks/HathiTrust have come through with a few over the past few years, which helps.
