Staedtler 510 Double-Hole Metal Sharpener, pack of 20

The Staedtler Double-hole metal sharpener features 2 holes for different sized pencils. The double hole design lets you sharpen pencils with a standard 8.2 mm diameter as well as larger 10.2 mm pencils, and works equally well with graphite and crayon. The ergonomic design features a finger hold for a firm grip when sharpening. Its metal structure allows you to sharpen easily, without breakage. The sharpener uses two different sized holes to ensure that both large and small pencils can easily be sharpened. One hole suits standard-sized blacklead pencils, using a narrower sharpening angle to help produce fine, accurate lines. The larger hole suits thick blacklead and coloured pencils, and aids in creating soft, thick lines. These sharpeners come in a pack of 4. Ideal for everyday school, home and office use.
