All you need is a bit of wire!
Make a little coil or knot or whatever you fancy at one end, then hammer the other end flat and cut the flare into a point. Finish it off with a file (an emery board works fine) - you can get a really sharp point with no difficulty.
It's worth hardening the wire before you start (a good tug holding both ends will do the trick) and give it a gentle hammer with a nylon mallet to harden further still when you're done.
I've made stick pin ends out of a bullet end cone filled with silicone in the past, though you can buy them I think.
If you run into trouble, I could do one for you if you like?
