Finally complete after months of work, Jon C. Acosta's steampunk-themed lightsaber is ready for battle. It being a concentrated cylinder of cool that combining a well-heeled Victoriana aesthetic and the best thing about the Star Wars trilogy, you absolutely cannot have your own one: it is a one-off.
Cast brass, leather-handles, and a soupçon of what might have been had Lucas riffed on Verne instead of old cowboy movies, it's a definitive work of fan-art. One imagines the distinctive growl of the extending saber concluding in an explosive hiss of steam.
A step-by-step on its construction is here.
