Circular disc strap cutting blades replacements

[Guest jsfarm]

I bought a vintage leather strap cutter and want to add and replace more blades. I have found blades but they are 70mmx40mm and my blades measure 88.9mm (3.5in) x 44.45mm (1 3/4in). I've looked online everywhere and cannot find anything close. Any help would be greatly appreciated. And can these dusc blades be sharped?

The make of machine would be helpful, as would be pictures, however you need to become a member to be able to post pictures here.
