This sword holds far more power than meets the eye, for when a royal bow breaks water, ye shall know her name and that of her enslaved crew."

The sword is more powerful than we think because when the Queen Anne's Revenge sets sail, we will know her [the ship's] name and the name of her enslaved crew. Blackbeard uses this crappy sword to keep his men in line, so it seems. Therefore the "enslaved crew".
