Staedtler Pencil Sharpeners with Plastic Shavings Holder & Lid for Graphite Pencils.
- Sharpener Enclosed in Plastic Case to Catch Shavings
- Safety Lock Lid to Avoid Spillage
- Available in Single Hole or Double Hole
The Staedtler 511 and 512 Pencil Sharpeners use the same alloy and carbon steel sharpeners as the 510.
They are enclosed in a plastic case that catches the shavings. The case has a safety lock lid to accidental opening and spillage.
The 511 is designed for standard 8.2mm diameter pencils to be sharpened to the optimum 23 degrees of angle which provides a clear and accurate line.
The 512 has the additional larger opening for thicker and coloured pencils up to 10.mm with a 30 degree cut angle for drawing softer broader lines.
