The compartment contained only a few items: the nude photos, the illegal charms book, and the remainder of Harry's knife collection. He left his butterfly knife (and its blunt trainer) in the compartment—it was too difficult for him to throw accurately, too intricate for Hermione to learn quickly, and frankly too showy for a situation where they'd only be pulling the knives if they needed to use them. For Hermione, he chose a combat knife with a fixed black blade, laminated canvas handle and perfect balance for throwing. That left him using his very first knife—a black folding utility knife. The balance was too far forward and the blade was designed more for wood than flesh, but he knew it very well. It was also responsible for a wicked scar across Vernon's chest, which was a nice plus.
