I wanted to share how I constructed the somewhat large sword wielded by MZMA from Black Rock Shooter: The Game. Here's a reference image for those of you unfamiliar with this character.
If there's one thing I learned from making this sword, it's that foam is an amazing and versatile material, hehe. Here's the link to the tutorial.
Let me know, either here or on the blog in the link, if you have any questions about how we used or obtained our materials. Home Depot and local scrap stores are awesome for these kinds of projects.
