Euro Cal Machinery Blade

[James Baldwin]

Hi, I run across this on the Shopgoodwill Auction site. A Shaper blade maybe? I don't have any use for it but I thought someone here might so I thought I would pass it on. Jim

Looks like a wobble dado blade to me. Different mfgs, but Sears is the most common. I have three, and use them on melamine shelving, rather than dull my good set.
