The dagger went a bit wrong again as I was cutting the foam, but luckily I was able to re-carve the foam a little to make it fairly decent. The problem is definitely the size of the point of the dagger, it is to thin so keeping it still as you carve is very difficult (you can see a slight “wobble” at the end of the blade in the picture below).
In the end the person I made it for didn’t like the bronze finish, it is a little on the orange side of bronze. My son however, really likes it

Had the chance to order some more foam recently so was able to continue with the spear. I covered the end of the fibreglass core with two layers of tough cotton to help prevent it pushing through the foam. Then after fixing the head of the spear to the core I covered the core with a layer of foam.
It looks a little on the thin side to me so I think that I’ll add another layer of foam to make the shaft a little thicker.
