Staedtler 510-20 metal double-hole sharpener is a durable, high-precision sharpener designed to handle both standard and thick pencils with two different sharpening angles.
Features:
Die-cast metal body for robustness and longevity
Two sharpening holes: one for up to 8.2 mm Ø (23° angle) and another for up to 10.2 mm Ø (30° angle)
23° angle produces fine, accurate points for standard graphite pencils
30° angle creates broader, softer points ideal for coloured and thick pencils
Three-point blade fixation for better stability and longer blade life
Deep groove allows easy removal of pencil shavings and broken tips
