By using a "return mechanism that ejects the pencil when sharpened," this product can avoid waste sharpening to a far greater extent than conventional sharpeners.
The operation is simple: just insert the pencil and turn the handle.
With a dust case lock mechanism, even if the sharpener falls, the shavings will not spill out.
Since it doesn't waste sharpening, it is also recommended for colored pencils.
Since you only need to insert the pencil, it is a type that does not pinch your fingers.
You can see the mechanism as it has a transparent body.
