1. A fixed-cutter earth-boring tool, comprising:
a first blade comprising a first blade body, the first blade body consisting essentially of a first material having a first elastic modulus at a temperature; and
a second blade comprising a second blade body, the second blade body consisting essentially of a second material having a second elastic modulus at the temperature, the second elastic modulus different from the first elastic modulus, wherein the second blade body carries a depth-of-cut limiter or a wear pad.
