Abstract
A knife sharpening device has two sharpening rods which are pivotally arranged on a base and arranged in a V-shape relative to one another to allow insertion of a knife therebetween. The sharpening rods each comprise at least one sharpening insert. The sharpening rods are held in a rest position at a predetermined distance from one another in their V-shaped arrangement by the force of a respective spring. The sharpening rods are spreadable apart in a sharpening position by insertion of the knife upon contact of the knife with the sharpening inserts against the force of the spring. The sharpening rods are held by a single holding point on the base.
