The Allen Key is a common tool in most mechanics and cyclists tool kits, but Daniel Neale was not happy with this design. Instead, he came up with a key called the 'D-Key,' which is half the size and allows for double the force.
The key does come in various sizes, but either way it's less bulky than the original Allen Key. For materials, high-quality steel was used, so users know that the device is sturdy for efficient use. What's more, is that this key is so compact that it can easily fit on one's keychain along with any other accessories. Cyclists and mechanics alike can keep the design in their pockets so that it's handy at all times, which is perfect for any slips that can occur while on the road.
