>My own Ian Knot (yes – I'm the inventor) is the World's Fastest Shoelace Knot. Make a loop with both ends and simultaneously pull them through each other to form an almost instant knot.

I doubt he invented that, because I've been tying my shoes with that knot my entire life and I'm 70 years old. My dad showed me this because it's the way he tied his shoes and he was born in 1912.

Ian probably re-invented it, like many people before him, but unlike your dad, and I guess, many other dads, he made a website, and the website became successful.

There are only so many ways to twist a string, and practical knots tend to be simple, knots get reinvented all the time before ending in a book. This is also why there there is no approximation in knox tying. If your knot is slightly different than what's on the book, it is probably another knot (see: square knot, granny knot, thief knot, grief knot), or just a mistake no one bothered to give it a name.
