Hi BillyJoeBob,
The Super commander is a larger version of the regular commander. The "newest commander specs" are switching from a plastic backspacer to a Larger G-10 back spacer that allows for a much stiffer knife. I believe that the blade grind is a little differrent also, along with traction grooves cut into the handle slabs and Ti liners. The original commander came out in 1998, and was offered in a hand rubbed satin finish as well as a black-t finish. These were built with thicker liners and handle scales. They are very sought after and often command high prices in the secondary market. It was based on a custom design by Emerson called the ES1-M, that was originally intended for military personell only. Mr. Emerson later decided to release a smaller version of that knife through his company. The Super commander is the full size version that is the same size as the original ES1-M. These are not regular production pieces. If you get a chance, get one, because they won't be around long. I've got a satin model heading my way. If you have yet to experience the wave, do so, no knife can be opened faster. Hope this helps,
BH
