I use a solid round billet of timascus polished and heat treated to reveal the beautiful rainbow pattern in the metal. One side features my signature with a small engraved Kraken logo. On the reverseside I milled a round cavity to fit another round billet of copper. This billet is chamfered on the edge and features small sqaure stampings. It is then placed back on the mill to engrave the large Kraken logo. Lots of texture and color pop on this piece!
