  • STANDARD PAINT includes a fully painted sword on both sides.
  • UNPAINTED is a more economical option or if you want to add your own creative touch on our piece. it is an unfinished option which means you need to sand, prime and paint and is offset by the discounted price.
  • PAINTED PLUS CLEAR COAT offers a protective layer that will increase the longevity of the product and gives a beautiful sheen.  If you wish to perform your own additional protection then we suggest Krylon Crystal Clear Acrylic Gloss.  We normally make 2-3 coats and follow the directions on the can.

Making the Finn Demon Blood Sword

Making Product

Finn Demon Blood Sword costume replicas are durable and lightweight.  Hand crafted from layered ¼” thick wood, providing structure and remarkable detail to create a replica as close to the original source as possible.  Specifically we sand, prime, paint, glue and micro nail each layer together creating a strong and durable fully immersive cosplay accessory.  Subsequently creating a highly decorated replica piece made for the imagination.  However, we do not encourage actual LARPing as paint and more delicate sections are prone to damage on collisions.

    Looks just like the photo!! Good craftsmanship. The actual blade part of the sword is pretty wide; that is my only issue with it but that doesn't take away from the rest of the sword, still fricken awesome and definitely worth it!
