I worked for a while with the fellow who sculpted the original raptor claw (he did all the teeth, claws, and eyes for JP). If you want to make your raptor claw "screen accurate" you need to cast it up like he did. He had an opaque dark resin "inner claw core" that he would place into the raptor claw mold (it had registration keys that held the inner claw in place and kept it from contacting the mold sides). The outer claw was cast in clear dental acrylic in a pressure pot. This made for a VERY realistic claw - much like a dog claw (translucent with a "quick" visible at the core). He'd then do some washes to bring out the insane detail of the outer claw's surface. I've never seen an "officially licensed" prop made in the correct fashion. It looks incredible, but it takes quite a while to pull off!
