So far I'm thinking of using pvc pipe and expanding foam.
I'd love to hear ideas on how to go about this. c:

Foam sheets might be better than expanding foam because of the large area and simple, flat shape.

You could run some wire through tubing for the center piece.

[Xaevier]

That thing is very complicated. I think you are going to have to utilize some sort of wood in order to get the shape right, expanding foam would never be strong enough at the ends to resemble a decent blade's edge, it would always look fat and fake.

Ah, ok thanks guys.
To be honest I'm (obviously) stuck.
And I've never worked with wood before.

Actually if you break it down it's a lot easier than one would actually think.
First off just break it down to the silhouette.
Cut THAT out of wood.
Add expanding foam and carve it to get the correct depth on everything.
Cover all the flat pieces in plastic (PVC/sintra, styrene etc)
Cover the curved stuff (the little jet looking things) in apoxie sculpt or plastic.

My biggest tip would be for where the handle meets the blade head, and the little jet things is to use a half circle guide to help carve the foam correctly. You can see it here on this picture how I use half circles to guide my clay sculpt for nice round domes.



In any case don't let anyone tell you that this is an impossible build. It will be time consuming, but it is totally in the realm of reason to make. I left a link to my Raven sword build and hopefully you will see how I broke down the sword. If you have any questions don't hesitate to ask!

Good luck to you and happy cos!

Thank you so much for the detailed explanation and link!
Lastly, ant tips for the blue tube-like parts holding it together?
I don't mean to ask so many questions, just don't want to mess up!

look into aquarium tubing. it'll bend easily and if u reinforce it with wire will hold that shape perfectly!

[StabbityBlkMage]

The tubing really needs to be wood, or at least fiberglass reinforced foam. They will have the highest load/volume ratio so they need to be as strong as possible. You'll just need a Dremel to get the wood round, or you can do this method of wood and apoxie sculpt (in the link I use bondo, but apoxie sculpt is more than viable).

See how I offset the wood on the sword so I can sculpt in a bevel with bondo? You can do the same thing for round stuff, and apoxie sculpt will help reinforce the blue tubing bits to hold more load.

Hope that helps. Don't be afraid to ask questions! We're here to help you make some awesome cos and I'm always available to talk some shop whenever.
