There is a symbol or element for every year of a wedding anniversary. After 5 years of marriage you graduate to wood. A carpenter I know asked me to build his wife a knife from a chunk of Honduran Rosewood that he created his wife’s temporary ring from while they backpacking through Patagonia. He said he carved the ring from the wood and then used sea glass as the stone until he could give her the real ring. I created this knife for him and used a sea glass green vulcanized fiber stripe to match the original colors. Both him and his wife really enjoyed the knife.
