A method of manufacturing a fan blade includes providing a fan blade blank including opposed major faces, opposed inner and outer extremities, and opposed first and second sides defining opposed first and second edges, respectively. The method further specifies cutting the fan blade blank asunder into first and second parts along a cut line extending from the inner extremity of the fan blade blank to the outer extremity of the fan blade blank inboard of one of the first and second edges forming a first cut edge of one of the first and second parts and a second cut edge of the other of the first and second parts, chamfering one of the first and second cut edges forming a chamfered one of the first and second cut edges, and affixing the chamfered one of the first and second cut edges to the other of the first and second cut edges forming a fan blade consisting of the first part affixed to the second part, the first part being angled relative to the second part.
