SOG's got me buying knives again after about a 15 year hiatus other than SAKs. I don't know if that is good or bad, but I know I have spent $1000's since on blades. It corresponds to the about the time I joined BF. Since then, my tastes have been refined a bit.
My first was the NW Ranger which taught me that I do not like partially serrated edges. My second was a Field Pup which I think is an excellent value. I have since purchased the Blink, Twitch II, Twitch XL, Access Card 2.0, Vulcan and Mini-Vulcan. I purchased the Mini-Vulcan at the blade show when it first came out. Love that knife. I also really like the Access Card 2.0, Twitch II, and Twitch XL. The Blink is too small for my tastes. The only one that I truly disliked were the Flash II's which I owned several as work knifes. They either got lost or stolen by my folks and it didn't bother me much as they had a lot of blade play. We abused them. None of the other folders had blade play. I especially like the Seal Pup Elite plain edge. The Revolver Hunter (pre-Fusion line) is a heck of a field knife if you find an aggressive saw useful. Have a couple Tigersharks, an original SK-5 and the one that preceeded the current one. They never fail to bring a smile to my face. The old Tech I and Tech II bowies are great knives also. So... I guess I own a few....
When they copied the Spyderco design, I stopped buying them. They didn't need to do that and I find it unforgiveable. Have not even looked at most of the SOG blades since although the Acess Card 2.0 is probably the last one I purchased and I really like it in VG-10. It makes a heck of a desk knife. The Japanese blades are quite good.
The question always comes up of value for the price. I have not been displeased by any of them except the Flash II. Would not buy another one of them. I replaced them with Spyderco Endura's.
