Two small javelinheads, typical spearhead and winged spearhead. Wings are peened inside the socket, and I also melted brass, in the forge, to the seam. Im not sure how the wings are attached in original pieces, but thats one possible way.
Spearheads weight about 400-700g, depending the size of the head. I use softer steel for the socket and middle of the blade and carbon steel for the edges. Other kind of constructions can also be used, ofcourse.
