The Serrated Bread Knife was a sharp utensil owned by Captain Blondebeard. He used it to kill a patron who complained about his Cajun style chicken.
Acquisition
Guybrush Threepwood pulled it from the back of the dead patron.
Usage
Threepwood used the knife to cut the leg from a sawhorse at the Field of Honor causing the rum barrel resting on it to roll away.
It was also used to saw off the plank of The Sea Cucumber forcing Mr. Fossey to tar and feather Threepwood.
