Adjustable Sharpness for 7-11.5mm Pencils

The sharpener accepts round, triangular, hexagonal and oval pencils from 7 to 11.5 mm in diameter. A three-level nib control lets you select sharp, medium or blunt points to match the task.

2000mAh Battery Delivers 600 Sharpenings Per Charge

The built-in lithium cell powers roughly 600 sharpening cycles before needing a recharge via USB. The helical blade is rated for 8000 total sharpenings, so the battery will need recharging many times before the cutter wears out.
