Description One sharpener for all pencil sizes? The 4-in-1 is the solution. Whether 7, 8, 10 or 11mm diameter pencils, you will hardly find a pencil that this sharpener cannot handle. Almost every pencil can be sharpened with the 4-in-1 into a perfect point. The world’s first 4-hole sharpener works with round, hexagonal and even triangular pencils.
