I was at the KTP a few weeks ago and was playing with what I thought was a mini-griptilian that had an assisted opening much like my kershaws. I liked it and saw one on sale online so I ordered it. Well...this one does not open like an assisted knife, it opens just like any other knife with thumb studs. I am trying to figure out if this is just defective or are there multiple versions of the mini-griptilian. The website is less than helpful.
