With its built-in sharpener, the previously-reviewed leadholder is useful, however, the Alvin Lead Pointer is the best way to keep this type of pencil sharpened. I am an architect and use these pencils every day. I’ve had this sharpener for more than ten years and it still works like new. The pointer is small, making it ideal to hold in your hand while rotating your lead holder around the pointer. Because your two hands are working together, I find I have more control and there are much fewer broken leads. The cutting head is sharp and lasts for a long time. It only takes a couple spins and your lead is needle sharp. Maintenance and clean-up is a snap. Take the top off the body and dump the graphite shavings into your trash and you are done If you do break your lead in the pointer, just remove the top and tap it on the inside edge of your trash can to clear the broken pieces. Lead pointers can be messy because of the fine graphite dust, but my pointer has never leaked the dust onto my desk. I have used many different types of pointers from desk mounted to ones mounted on the top of an electric eraser. The desk mounted pointers tend to break leads easily, since you are moving your lead holder in a circular motion around a pointer fixed to your desk, thus you may move in a direction that is not compatible to the pointer and will snap your lead. The electric eraser type is good, but it does not stay sharp for very long. It’s also difficult to empty the graphite shavings and jams when you break your lead inside it. This pointer really is the best way to keep you lead sharp! If you work in an office, you may want to buy two — because it is so small and useful, your pointer just might grow legs.
