I would say it is not that of an problem if they go down fast. Without any pictures its hard to say if it is because of the way you sharp or the way you draw. It is possible that you press to hard though. In my experience the differences of sharpeners are not that big. If your pencil is sharp at the end, its fine. If you are going to use a blade they will probably run down even faster because you will brake a few in the process.
