At the bottom of the Wikipedia page was a link to the Creepy, Abandoned Chi-Chi's Blog, which is a great idea but kind of sad and light on posts right now.
But they did have a link to the Belt Buckle Knife site, which I still think might be a parody, because it includes this line straight out of Real Ultimate Power:
Ok so you may have some really great knives with fancy handcrafted blades that will cut through any known material on earth, but no matter how great it is, it still has the same inherent problem that all knives except ours have. You have to get it out.
Also, its tagline is "How fast can you whip yours out?" I guess I'll find out if it's a joke when I try to order Mr. W one for his birthday, because I am SOLD on the usefulness of having a knife on your belt buckle..
