I have a couple Marbles blades that are from before their plunge to china and downhill.
These blades were never assembled and will have some of my "custom" hand grinding.
Blades were from Marbles to their outsource grinder from just before they pooped on their US suppliers.

I might be able to replace your tired Mables with near exact same blade if interested.
