Want to see things get sliced and diced from the sword’s point of view? Of course you do. That’s what we are here for. This video from YouTubers Sam And Niko shows what happens when you mount a GoPro to the blade of a katana, then watch what it sees as it slices through things. The video shows the whole process from the initial experimentation to the final shots, so it takes a bit to get into the POV slicing action.
