Let's make the sword.

Draw out the sword on your sheet of foamboard.

Here is a look at the handle and base of the blade.

And here is how to draw the tip and the hook.

Once you have the sword drawn out go ahead and cut it out of the foamboard. Then make a copy of it by placing it back on the sheet of foamboard and tracing it. You want two of them for strength.

Cut that second one out then glue the two of them together. Having a double layer sword will make it much stronger. And... if you only had a single layer it would potentially warp when you painted it. With two layers glued together it will resist any warping when you paint it.

When you glue together two layers like this there will be some rogh edges. Clean up the edges with a hobby knife and/or some sandpaper.

Next we will make the guard of the sword. Continue
