Take the Hover Crate into the Firing Range and jam the glass door with your body. Load the crate with knives and Remote Mines by throwing them onto it. Take it up to the gadget lab, then go back to the firing range and detonate the crate upstairs. When you start gadget training, you can now pick up one knife at a time but it should be worth ten knives, and you can use them on the people in there.
