The main function of a pencil sharpener is to sharpen pencils.

I. Core Basic Function: Pencil Sharpening

It sharpens pencil leads into sharp tips of appropriate length for writing, doing exercises and taking notes. The tip thickness can be controlled to ensure smooth writing.

Drawing Pencils (2B / HB / 6B, etc.)

Specially designed for art sketching, hand drawing and engineering drawing. It creates long conical lead tips, ideal for large-area shading and fine hatching.

Wooden Colored Pencils
