Abstract
The invention relates to a sharpener for sharpening a cutting tool, such as a knife, the sharpener comprising a body part (), a rotatable sharpening roll () resting on the body part, and a first guide groove () above the sharpening roll for receiving a first tool blade and for guiding it in relation to the sharpening roll (). To allow the sharpener to be made structurally simple and well applicable for sharpening both narrow and wide blades, the sharpener comprises a second guide groove (), which is wider than the first guide groove (), to be arranged above the sharpening roll () to allow a second tool blade to be received and guided in relation to the sharpening roll ().
