Outer collar - Basketweave Damascus, Inner Disc - Copper, Stem - Flamed Titanium. The BW Dammy is a beautiful darker steel, so gorgeous along with the copper and purple flamed ti, awesome in hand. This K2 is HIGHLY sought after, one of the most beloved combos that was made, and there was a smaller number of them made, so they are hard to come by. Rare, awesome opportunity here!
