Here is a tool I recommend for anyone who likes sharp pencils all the time. Whereas I like and use a rotary pencil sharpener in the workshop, when i am out and about I found I had to be ultra careful with my leads because many pencil sharpeners are poor when developing a point, often breaking and rebreaking the leads. This one I love. It has some good points about it besides lead ones. In the main body of the sharpener are two conical cutter receivers. One for the wood and one for the graphite. It’s a two stage system for sharpening and it works to deliver really long and sharp pencils. In the sides of the sharpener are two more holes, one for a thin lead and one for a thicker one. The blades are sharpenable too. It’s made in Germany by Kum.
