Möbius & Ruppert - Brass Round Double-Hole Pencil Sharpener - 1438599

Yes, it is excellent for colored pencils, provided the wood casing is standard (6 mm) or jumbo (11.2 mm) size.

Yes, the high-carbon steel blades are designed to be replaced, ensuring the tool lasts for years.

Brass can develop a natural patina over time due to contact with air and skin oils; this is normal and many users prefer the vintage aesthetic.

The larger hole is specifically designed to accommodate pencils up to 11.2 mm in diameter.

While it is a functional tool, it is a precision instrument and not a toy; adult supervision is recommended for younger users.

Check if the blade has become dull and needs replacement, or ensure the pencil is not being pressed too forcefully into the sharpener.

Gently clear the throat of the sharpener with a thin, non-metallic tool like a wooden toothpick to avoid scratching the interior.

Inspect the blade screws to ensure they are tightened evenly and that no debris is lodged between the blade and the brass body.
