Replica Props Forum user Indakin built a pretty detailed Peter Pan costume inspired by the one Robin Williams wore in Hook. He especially wanted to get the golden sword right. He commissioned a base sword made from bronze, and then he studied hundreds of stills from the movie for reference. He eventually crafted his own sword once he realized the bronze one was a little too heavy for carrying around conventions:
For making my own sword I wanted to get the proportions even more accurate to what i had seen. I also used a coconut shell (smaller in scale this time), wood trim to make the grips, and an aluminum bar to make the blade. Dremmeling the blade to shape, and cutting the coconut were quite the pain in the but. The Coconut was sooo strong to cut through, took a while. The aluminum cut easier, but the metal would build up on my grinding wheels and then wouldn’t work as well. I added deep grooves into my wooden grips, so that when the leather was wrapped, it would fill in the grooves and leave a visable texture, like the movie hero version presented at the end of the film. The pictures should speak for themselves a bit. I did a bunch of detailing after it was finished too. I used barge glue for attaching everything together. I spent about a full day making my sword. I know how the original was made now too, but my methods work well enough and look the part… plus with this version i can actually cross swords a bit without fear of killing someone.
