If I am not mistaken, there were a 5.5", 7.5", and the monster 9" blades made. If I remember correctly, the first ones were ground by Scott Cook when he still worked for CRK. Those were the 7.5" versions.
I used to have the 5.5" and the 7.5" versions. They both have impressive grinds and are built solid. They are really beautiful knives, but I sold both of them as I did not think that I would ever use or carry them.
They were made with the same specs as the current one piece line.:thumbup::thumbup:
If you want it to collect, then depending on the price, it would be a good acquisition. If you want a user, you would be better choosing a different blade. Not that it would not be a great user, but it will be to collectible to use-IMHO!
