For a college project, we were asked to make a snake ring from a piece of sterling silver square wire.
We had to use a draw plate (google it!) to draw the metal from a square shape to round. We then had to hammer one end to 'spread' the metal out to widen it (for the head shape) and file the end so that it tapered to a point for the tail.
It was actually a lot more difficult than it looks, as with all the hammering/bending/shaping the ring became very stiff and hard to work with very quickly. Also, I had to be super careful with the tail as it was so delicate, but all in all I think it turned out OK for a first attempt!
