The Katana Bookends by Mustard make it look like your books have been impaled by a Katana sword. It’s a clever set of bookends with hidden brackets, with the plastic handle stuck into one end of your stack of books and the blade pushing out the other end. It’s a mighty and metaphorical sword for literary ninja bookworms who are capable of gnawing their way through an entire set of books in a single sitting. It also makes for a great conversation starter, since it’s hard for a guest to see it and not say something about it. It goes without saying that this is an ideal gift for comic book and superhero movie buffs, since it works just as well with DVD collections too.
