An online knife manufacturer boasts their design of what they call the “world’s fastest knife,” attributing this quickness to being stored inconspicuously – and highly accessible – as a belt buckle. An animation on their website demonstrates how quickly it can be removed from the belt and swung open, making it appear as a faster draw than a switchblade. Watch for these, they are available to the public for just over $100. View the manufacturer’s website for more details.
