User blog:Bedengo/Vampires knives or razorpine?

Usually I just run, jump and fly while attacking with my vampire knives, but I heard that the razorpine is better than the vampires knives, I've survived the frost moon many times and never dropped it yet, should I still trying to drop it? Which one is better vampire knives or razorpine? And why did u chosen that one has better?
