This magnesium alloy pencil sharpener uses a 1-hole tempered steel blade and has a block profile with a recessed grip area. Its high-carbon steel blades are incredibly durable and sharp, thanks to the dynamic torsion action built into each blade. The design of these sharpeners allows for a more precise angle, creating a smoother and cleaner cut. The included quality blade is made of specially hardened steel, measuring 1.22″ long (31mm) by 0.65″ wide (16mm) by 0.62″ high (15mm). Made in Germany.
