Abstract: A portable, handheld sharpener having an elongated body with loop attachments, a battery-operated DC motor with speed reducing gears and a gear plate and a rotatable sharpening unit. A pouch-shaped waste shavings receptacle detachably attached to the body provides a larger cross-sectional dimension ergonomically contoured to fit within the grip of a hand while providing increased internal space for waste shavings storage. An actuator button is molded into the receptacle and is partially circumscribed to provide a hinge-like action to engage a leaf spring connecting the battery source to the motor and also provides a momentary operation of the sharpener while in the original retail packaging. The actuator button will not operate when the receptacle is detached from the sharpener and the internal sharpening unit is exposed, thus acting as a safety feature.
