A little something I learned about wrapping these is to get you a small pair of dikes, and some round nose plies.they sell them at walmart as a set, in the crafts sections for a small fee.If you use regular needle nose they will mare the wire and not looks as good on the twist.
Also, it's a a good idea to leave the base of the point straight across,as any notches/concavities will make it tougher to get a good clean spiral on the loop. You can see it on the Cahokia point. I'm gonna have to redo that one.
Also, be sure to grind all edges of your points,If the edge is left sharp it can cause some neck/chest problems in the heat of the moment.
