I searched it and it took me a little to find the one I have. Apparently they make several versions of that knife. This is the one I have and for less than 1/2 of what I paid at the time.

I just looked at the picture and it has the same lock button and safety lock to stop it opening prematurely but not an auto like I have.
Here is the auto. Remember this is a cheap knife but like, I said, I have been using mine for about 10 years now and it has never failed and as I said I really abuse it. Don't look for great fit and finish but it is a great knife for the price. Mine holds an edge for quite a while too even with the abuse.
