A few dozen years ago or so a company called Albion Swords started producing a beautiful version of Lady Vivamus (http://www.albion-swords.com/swords/albion/late/sword-lady-vivamus.htm). Their sword is "endorsed" by the Heinlein Prize Trust. And it is very expensive. I would love to have had one of Albion's Lady Viviamus swords but could never rationalize the $3,000 price. I had originally posted here that the Albion sword was no longer available but that turns out to not be true. I recently (2017) contacted Albion and they are still making the sword, still at a very high price that doesn't include the scabbard. The Albion Lady Vivamus is given to the winner of the Heinlein Prize. The first winner was Peter Diamandis.
