Yes a score in football! I felt like it was a game winning score when I got that knife last night.
Igor, around 1989-1991 Buck was producing some knives and knife series patterns in picked bone. Brown and Red were the colors available. The 110 got brown and red and a carbon steel damascus. I've also seen the 110 in red bone satin steel from this period. The 500 series was made in brown bone for just a couple of years. IMO, these bone knives rivel the stag knives from that period in desirability. They are certainly much less common as Buck never produced the quantities of bone knives that they did in Stag especially if considered over time.
The steel in the early 90's was 425M.
