As Geroli suggest stone a slight radius on the tip, and while you are at it, stone the ground surfaces as well.
The look on your tool edges resembles a sawtooth, they should look polished and razor sharp. A normal chisel sharpening fine oilstone will do you for now, and can be picked up at market stalls for a couple of squid. You only need to sharpen the very fine cutting edges, not all over where you have ground.
The finish on the turned metal should be like polished steel.
Speed and feed charts are NOT foolproof, they are for a rough guidance only. They are really for use in production work, where they can have total control over the material specs and machining tolerances.
