what you guys think of sharpening like this?
That. Besides: why is people always reinventing the wheel?
Why did Takeda make their own hand held sharpener? https://www.youtube.com/watch?v=n7iVKRmmTNY
I try to only judge results.
Well, there's always a talented unique. It's like in golf, the swing of Jim Furyk, weird, exceptional and efective, but not really worth imitating.
That's not the case of the video.
People should learn the traditional way and have a solid understanding of basic concepts before making up techniques. The ones that learn starting with these, let's call them fringe techniques, are at a big disadvantage. It's harder to unlearn and relearn.
It's too late for me to even make small changes. I want to try sharpening sitting down, but I already have the muscle memory from sharpening standing up.
