I'm working on my fett costume on a real tight budget, so I've been runnig all over the place looking for cheap materials. I went to a place called Cabela's, a large hunting and fiishing store, looking for possible blaster parts. What I found in the fishing section were a type of line weights called bullet weights. They come in different sizes from the size that would be about right for gauntlet darts to the size that would be right for boot spikes. They were kind of pricey there, so I checked and they have them at Walmart. I bought a pack to use for my gauntlet darts. There metal, the right shape, size and the pack was less than a dollar. Cheap and not as messy as a bic pen. Just thought I'd pass along my find.
