These kinds of huge tailors' shears are not available anywhere anymore. They haven't been manufactured in 35 years.
The original factory that has the original forms for them. They are willing to re-manufacture a run of these if there were enough orders.
Is anyone interested? It's a rare opportunity if you're into this kind of thing.
I've been looking for a high quality set of shears forever, and the change to get a pair brand new is something I don't want...
