My original darts were made with a nail, a ball point pen tip, and a bit of vinyl tubing. but because the glue surface was so small the tips kept getting knocked off. So I cast them in resin and again because they are so small they just snap in half if someone looked at them funny. So I decided to try and use the mold from the resin ones and cast them in a metal alloy. I still have to clean them up a little and hit them with dull coat, but I think these will work out better.
