Drawing and Painting instruction for Children and Adults
Hello, Great question as sharpening them the "proper" way is a bit of work as we both know. I suggest using the metal tin that a complete set of pencils come in (not necessarily those pencils) as it is designed exactly for what your trying to do. I use Staedtler pencils - made in Germany and widely available. Best, Jonathan G. www dot jonathanfineart dot com
