Downhole tools with fixed cutters for engaging subterranean formations, removing rock, and drilling wellbores may include drill bits (e.g., polycrystalline-diamond compact bits) adapted to smooth torque and to minimize vibration during operation. The drill bits may have alternately arranged or designed blades. In some cases, one or more blades of the drill bit may have a wave-shaped blade. In some cases, the drill bit may have multiple blades with patterns that differ from each other in shape or orientation.
