On the surface, General Manufacturing’s new Derby City Brass Money Clip looks like a cool, simple way to hold up to 20 bills, or 10 bills and a card or two. The flat spring is available in standard yellow or white brass and manufactured by hand in New York. The way that it’s made is where things get interesting because each clip is made with the ancient lost-wax casting process. The same process that artists have been using to make bronze sculptures since 2000 BC is used to make these money clips. The process basically breaks down like this: create model in wax, make mold of model, create hollow wax cast using mold, create fire-proof mold around wax, cast in metal, break off fire-proof mold. The fire-proof mold and wax cast are generally both lost in the process, hence “lost-wax.” That’s a lot of work for one money clip.
