Vintage Wiss Model-E Pinking Shears help

[chicisme10]

I have a pair of dull WISS Model-E pinking shears from the 50s. They can’t be sharpened because the blades are supposed to be replaceable, but I can’t find any blades online. Does anyone know where I can get vintage blades?

Thanks in advance,

They could probably be sharpened a few times which would thin the blade and shorten the retention screws. Or contact Weiss for a recommendation.
