Based on the Honshu Karambit.
The knife was masked to protect the handle. The knife is polished to a shine. Then the surface is cleaned using metal prep which helps the paint adhere. A transparent yellow/gold coat is applied, then knotwork vinyl transfers are applied to the blade. Finally, a clear coat of Cerekote is applied. Cerekote is a durable clear coat used on Guns. The clear coat will resist most minor scratches, but scratching hard objects like rocks or metal can damage the paint.
