It is unknown how Boostrap Bill Turner came into possession of the black knife, but it would be in his possession up until his service aboard the Flying Dutchman. Shortly before his son, Will Turner, escaped the Flying Dutchman, "Bootstrap" gave the knife to him. Will promised to use it to stab the heart of Davy Jones and free his father from servitude. Later, as the Kraken attacked the Edinburgh Trader with Will aboard, he used the weapon to slice through a sail, stopping his fall.
During the battle of Calypso's maelstrom, Will was forced to fight "Bootstrap" who in his madness didn't recognize Will. Defeating his father, Will used the knife to hold his father down while he saved Elizabeth. When Will was fatally stabbed by Jones, "Bootstrap" looked to his left and saw his knife. Instantly, he recognized it, and Will, and broke free of the knife's hold to attack Jones. After Jones was killed by Jack Sparrow's sword, "Bootstrap" took up his knife again, and with the rest of the crew near him, used the blade to carve out his son's heart as he died, thus resurrecting him as the new captain of the Flying Dutchman. The knife's fate is unknown.
Behind the scenes
- This knife was named "William 'Bootstrap Bill' Turner's black knife" in one of the previous versions of the official POTC website.
- In the At World's End video game, Will is shown to have his father's knife on his belt during the whole game, even before he met his father on the Dutchman, this is possibly a design error because Will was given the knife by his father.
