I tried to buy the Mini-Culloden from Cold Steel several times when it was in their "close-out" section. Each time they were out of stock. Today, I searched their site for it, and it directed me to their replacement, which is a folder, not a sock-type knife, and it's about 10 times the price of the Mini-Culloden.

Good luck with finding it. If you get one, I'd be interested to hear what it's like. Cheers,
