This foam sword pops out of a coffin and stabs someone! Since we couldn’t fit a whole sword in a coffin, and we couldn’t stab anyone for real, I made the sword in two halves.
The front half to pop out of the coffin (I rigged it to operate pneumatically,) and the hilt, which has a flat base to attach beneath a hole in the actor’s clothes. The blade is made out of silver-painted foam, and I was able to get a serrated effect by wiggling the razor blade as I cut. The hilt was made out of a goofy old gold lame’ belt, which I brushed with a light coat of brown acrylic paint.
