A heads-up to all who are interested in owning a functional cutter (as opposed to a man cave decorative antique):
Getting old choppers to actually work the way today's pipe smokers ASSUME they will takes a bit of refurb & enhancement.
The blades they were originally equipped with were thin and flexy, designed to cut off lengths of sold-by-the-inch rope in general stores. That's it. They were not designed to slice plug into neat 1.5mm slices, loaf-of-bread style. That requires a much stiffer blade that's flat on one side like a sushi knife, and sharpened to where you could almost shave with it.
Such a blade must be custom made when intended for a particular model of antique rope cutter, of course.
Then, once you have a good blade, the entire surface leading "up to" it from feed side must be made level. That means cutting free the staked brass piece that receives the blade's edge (it's there because iron would instantly destroy a razor edge), grind it to dead-flush and reinstall; and then fabricate an equally level platform for the plug to rest on while it is indexing forward. Not doing those things will make slicing a plug a tedious, frustrating process with a messy result. (Delaminated leaves, thick & crumbly slices, etc.)
