What is the difference between Tunisian and cro-hook?

Tunisian crochet is the term for any crochet in which you use a long-ish hook. You open the stitches on one "pass", then you close them up on the second "pass." It's very similar to knitting, although thicker since it takes two passes in order to complete the row. The Tunisian hook, also called afghan hook looks like a knitting needle with the "knob" on one end, but a crochet hook on the other instead of a point. You can also get the same thing with a hook on each end, a double-ended afghan hook.

For the most part, most people are familiar with the afghan stitch. But, this is just one stitch in the Tunisian crochet family. There are many others and many combinations, just like regular crochet.

Boye and Susan Bates both make the hooks. There are regular afghan hooks and there are those with the extender cable. There are regular double-ended hooks and there are those with the cable. In the 70s, Mary Middleton introduced "crochenit" which is double-ended Tunisian using only a size M hook. At the same time, Boye and Susan Bates were using their double-ended hooks and the technique was called cro-hook or cro-knit, depending on who the publisher was.

In the 90s, crochet with the double-ended hook became widely known as Crochet on the Double when many new patterns were introduced by Annie's Attic in this technique.

MoEZ is the name given the hooks made by Monte Grimm. They are both regular Tunisian hooks as well as double-ended hooks. Instead of a knob on the end of the Tunisian hooks, I believe he has dipped them in some type of rubber, color coding the rubber for the size of the hook. They make larger Tunisian hooks from about a size L and up.

For regular Tunisian, you work with one hook and you don't turn your work. For double-ended Tunisian (cro-hook, cro-knit, crochet on the double), you turn your work and you use to separate balls of yarn, one for each hook.
