A knife sharpener is provided which is capable of precision sharpening of hunting and similar knives that have a first and second blade face, each of which terminates at a facet that meets the corresponding facet to create the knife edge. At least the first of the blade faces has a lower distinct planar or concave section adjacent the edge facet with the lower planar or concave section of the face being set at an angle to the center line of the blade thickness that is different from the angle of the adjoining upper section of the same blade face located adjacent to the back of the blade. The sharpener includes a sharpening member such as one having an abrasive coated surface. The sharpener also includes a planar angle knife guide surface of a knife guide which is designed for intimate sliding and sustaining contact with the second face of the blade in order to position an edge facet on the first of the faces into precise angular relation with the sharpening surface. The sharpener also includes a knife holding spring that applies force against the first face of the blade predominantly at one or more locations on the lower planar or concave section of the first face that is adjacent to the edge facet being sharpened in order that the lower section adjacent the edge on the second face of the blade is pressured to align with and remain in intimate sliding alignment with the guide surface as the blade edge facet on the first face is being sharpened.
