When we last saw master bladesmith Tony Swatton, he made a fully functional axe modeled after Gimli's from The Lord of the Rings. Most recently, he created a battle-ready version of the bat'leth, a sword from Star Trek. Qapla'! His tempered steel sword is ready to sever Jem'Hadar heads.
At the link, you can watch a video of Mr. Swatton making the sword. Be sure to watch until the end, which shows his assistants attacking targets with the bat'leth.
