Summary

I wanted a glowing bladed knife for a sci-fi cosplay costume. So I designed this one. I used the handle from Herman_Lundgren's Bayonet (CS:GO Knife), because I felt it had the right sort of military sci-fi look.

It is designed to fit the common 20.5cm by 0.5cm (8"x1/4") glow sticks, which I get in packs of 50 for a few dollars. They are the ones used to make necklaces and bracelets. They just slip in the hole in the base, and press into the socket at the tip. I find they are a close enough fit that they don't move about, but if needed you could just wrap a bit of sticky tape around the end of the glowstick, and it should hold it in place quite securely.

The plastic doesn't quite transmit as much light as I would like, but if you put the glowstick in boiling water before breaking it the light is very bright.

This is a prop, It doesn't have an edge, and will likely break if you tried to stab someone.

this is so awesome. try printing in carbon fiber... :o

I should also point out; This knife is NOT for stabbing or cutting with. I deliberately designed the blade to snap off for safety reasons. I also made it practically impossible to sharpen. Even if you did print it out of carbon fibre, you won't be able to put an edge on it and it will break very easily. While you can hurt someone with it, a good sharp pencil would be more dangerous.

I was planning to try carbon fibre at some point... not sure how translucent it would be. If I get it to work, I'll let you know.
