An airfoil according to an example of the present disclosure includes, among other things, an airfoil section extending between a leading edge and a trailing edge in a chordwise direction and extending between a tip portion and a root section in a spanwise direction. The airfoil section defines pressure and suction sides separated in a thickness direction, and includes a sheath having first and second sheath portions extending along an airfoil body of the airfoil section. The first sheath portion includes a first interface portion, and the second sheath portion includes a second interface portion that cooperates with the first interface portion to establish a joint having a circuitous profile along an edge of the airfoil body. A method of assembly for an airfoil is also disclosed.
