Hmmm... too completely unrelated questions.How thick a slab of steel did you say that sword cuts trough?How thick is the hull of the ship?

The problem is that it's a large plate of solid steel. The Crimson Blade is sharper than any blade, but it doesn't have any mass. It's weight is little more than that of a wooden stick, which means it's relatively useless at cutting through heavy armor. It'ss slice through pretty much anything, with a vampire's strength it's even cut metal, but you're going to be banging your sword against a large wall of steel. If you really wanted to get through, you'd want some form of drill, a lasersaw, maybe. Heavy-duty lass cutters, fueled by magnesium. Those babies can go up to 700 Celsius.
