What's the angle? grinder that has two small circular blades going
the opposite direction? Specifically, what does harbor freight call
their cheap one? I suddenly need one, I think, but can't get it
because I don't remember what it's called. Thanks.

(There used to be one advertised on late-night tv.)

You mean the Dual Saw with Billy Mays ?

I've not seen a dual blade grinder.
