For those who’ve been keeping an eye on Valyrian Steel—the only official producer of replica weapons based on A Song of Ice and Fire, with direct input from George R.R. Martin—their latest creation, King Robert’s warhammer, is finally up for pre-order. It’s a massive thing, and there’s a nicely illustrative video that gives a sense of how hefty it is and what sort of damage it could do (note: no, you shouldn’t actually use this to hit anyone!)
Besides the warhammer, they’ve created Longclaw and Needle, as well as Ice (including an extremely limited “Damascus” version). I believe their future plans include Khal Drogo’s arakh, an obsidian dagger, and more.
