Flush from the sale of some of my own brand of "well curated vintage Americana", I ran a Google search for "scrimshaw tie clip", or something. I wound up at the Pierce website, a website so quaint in its very 1997-ness that I was immediately reminded of the pleasant experience I had a while back with Arrow Moccasins. They offer a wide range of scrimshaw products, from knives to jewelry, to carved teeth, and even a really killing shaving set. Pieces are made to order. Everything they make can be done on shed antler (i.e. antlers naturally shed by the animal and later gathered in the woods), which is what I opted for, or for a bit more on fossil ivory (i.e. old ivory found in Alaska). You get to pick the design, and they even do custom work. My piece arrived a scant two weeks after placing the order, a mere $28 shipped. Seriously.
It arrived in a small jewelry box lined in cotton with this business card sized certificate of authenticity. Usually, such certificates are totally bogus, but in this case it's the icing on the cake.
I could get all descriptive and flowery, but I won't, because I don't have to. Buy something from these people now. You won't be disappointed. Take my word for it.
