What must your sharpener do?

Measure the widest point of a representative pencil shaft in millimeters. Leave blank if you have not measured. The finder requires a documented range; 'fits nearly every pencil' is not a numeric range.

A product's 'ideal sharpness' wording is the manufacturer's description; it is not a measured point length or a guarantee for every pencil core.

A signal shows the manufacturer-described completion state; it does not measure point length or sharpness quality.

This is distinct from an automatic stop at the pencil tip. Check that the bin is seated before operation.

A named gear design is not a guarantee for every soft or waxy colored-pencil core; read the model-specific caution.
