For the Geneva sisters Anna, Sarah, and Geneva (aka Three Little Mice, Tayaya, and Geneva D), creating with LEGO is a family affair. The three talented builders collaborated on a series of life-size swords to showcase at this year’s Brickworld, each forging a personal blade with its own personality.

Using brown and metallic silver (and a touch of Spinjitzu!) on the hilt for a studded leather look, this is clearly the blade of a warrior. She pairs the sword with the smaller and more play-friendly dagger, Acheron, which boasts a serrated blade and a menacing Hero Factory spiked ball on the hilt.
