I like to make my spears out of metal for two reasons. It takes paint better than broom bristles and if there is no ring hand (or I can´t create one) they can be heated over a candle and "welded" to the bod. It has a disadvantge in that it´s heavy but as my bods all get based, one way or another it doesn´t bother me.
Firstly the tools. From right to left. Pliers (I forgot to add them in the pic) fine metal file, hammer, an old pair of scissors, 0.8 florist wire, and a hard surface. I´m lucky cos I´ve got this little anvil..(I pinched it from my son...well..he pinched 2 of the robots I got the other day ...so fair´s fair).
Cut of a length of florists wire..a bit longer than the length the spear will end up. Bash the tip flat, ocassionally turning the wire over so that the "spearhead" will end up more or less central to the shaft.
Snip the basic shape of the spearhead. A pair of old scissors work fine as the metal should be quite thin after it´s beating.
