I actually use blackboard chalk too. I have a piece of sticky back sandpaper on the side of my table. Right over the trash can. I sharpen the chalk by rubbing it on the sandpaper after each line.
I don't try to make a two sided chisel edge just sharpen it on one side sort of like the point of a hypodermic needle.
