When you hold a pencil and begin to write or sketch, you likely don’t think about the engineering precision that went into its creation. Yet, one of the most critical — and often overlooked — aspects of pencil manufacturing is the alignment of the graphite core. Known in the industry as alignment tolerance pencils, this […]

When you press a pencil to paper, the mark it leaves behind seems simple — a dark line, a soft sketch, a precise letter. But behind that mark lies a complex interplay of materials and manufacturing choices. One of the most overlooked yet crucial factors in this process is graphite density, a property that directly
