A blade sharpener which has two elements, one of which is a hand-held member, and the other of which is a follower member secured in the hand-held member is disclosed. The two members are pivotally secured each to the other, and secured at variable pre-selected pivot points so that adjustments can be made for the particular skate, and for the particular cross-section of the blade desired at various points along the power toe section, neutral underfoot section, or turning heel section. Means are provided interiorly of the single hand-held member to optionally secure a file of the varying cross-section. Guide means are supplied on the hand-held member to secure the relationship of the abrading member to the intended blade in a pre-selected centralized orientation. The guide means can be varied in their special relationship to accommodate varying thicknesses of blades. The method of the invention contemplates sharpening a blade by longitudinally stroking the same with a single file having a pre-selected cross-section and which is guided in a fixed relationship to the blade by a single adjustable pivot member to thereby develop the desired cross-section or cut of the blade at various points along its length.
