Hi guys. I would like to share some pics of a knife I recently picked up and have some questions about. I know that it was made by Tak Fukuta in Japan and that is a SOG pattern knife. What I would like to know is approximately when was it made and what kind of steel was used? Is it rare? I haven't been able to find much info on it. I paid $315 for it. How did I do? Thanks in advance.
