    They are two different animals.

    Unihead;

    Univise, this is a chicom clone being sold by Tools for Cheap. It differs somewhat from the Rockwell, but is functionally the same;

      The Unihead holds a collet that in turn holds the tool to be ground (much like a 5c Spindex). They are Brown & Sharpe #9 taper if I recall correctly. The Univise holds the tool directly in its jaws and can be used to sharpen faceted tools such square or rectangular planer, shaper and lathe bits.

        The one I have is B&S #11.

          Yeah, I think I have one kicking around here somewhere too. Whatever the taper is, it's not anything currently common so they're kind of a PITA to tool up.

          Hmmm, now I'm wondering if my KO LEE head might also be the same taper, but it has a sleeve to adapt to a 5C collet taper. That's why I use the KO LEE and not the Unihead.

            must be a hybrid...

            Thanks for the replies!
            Evidently the RW versions used the same base casting (except for the name). I just looked at one that has "Unihead" cast into the base and the business end has jaws similar to the offshore knock-off.

              A detail no one has mentioned. Neither are meant for use on a milling machine. Both are grinding fixture and lack the rigidity for milling.

                Yes,I recall the univise literature from the 60's,for grinding tools. I have an old,but unused univise now.
