Star Wars Unleashed replacement lightsaber 'blade' to scale
My wife is a big collector of the older Star Wars Unleashed figures (the 7" larger figures) and we have 2 young boys and 3 young cats that make off with the little lightsaber parts. This file is scaled for the Obi-Wan figure from series 9. It fits all of the standard figures except Yoda (but you can scale it down to fit) and those that have silver lightsaber parts molded into the light 'blade'.
Works for us -- use it to re-build your neglected collection.
