Slightly OT, celtic design metal engraving

I just ran across this on ebay, a sax profusely engraved with celtic knot type engraving, all hand done. Ebay auction #3780716419. Or check out his website www.dumarsengraving.com. This guy does outstanding work restoring and re-creating classic patterns as well as custom designs. His website features photos of mainly 20th century sax’s and brass, but I imagine he could do custom work on any piece of metal.
