A turbine blade (100) includes a convex suction side wall (112), a concave pressure side wall (110), a tip wall (114), an internal cooling circuit (146), and a plurality of tip edge channels (144). The tip wall (114) is recessed from a first tip edge (130) of the suction side wall (112) and a second tip edge (132) of the concave pressure side wall (110) to define a suction side wall tip section (138) and a pressure side wall tip section (140), and the suction side wall tip section (138) is shorter than the pressure side wall tip section (140). The internal cooling circuit (146) is formed at least partially between the convex suction side wall (112), the concave pressure side wall (110), and the tip wall (114). The plurality of tip edge channels (144) formed through the first tip edge (130) of the convex suction side wall (112) extend to the internal cooling circuit (146). Methods of manufacturing turbine blades (100) are also provided.
