I watch the video and many inventions seemed super important and innovative, but there was one that I really liked. Klax is the ax head that has a clamp system allowing it to be used next to any stick and thus be able to take the ax head to where you want. And there was another one that seemed like a waste of time. Tap strap seems to me that it is the worst invention that is shown in the video, when you are writing you can not see the keyboard, and normally people need to know where the keyboard is in order to write. But this invention what it does is that you write where you want without being able to see the keyboard. But why want to compare a good invention and a bad one? I sincerely believe that the ax is very simple but extremely practical but if we realize the keyboard seems an unfinished project, it is a project with very good ideas but needs to be improved so that everyone can use it. So if the company improve Tap strap this will be one of the best inventions.
