This fellow is due for a Darwin award any day now. Death will probably not ensue but I'd prefer a vasectomy with anesthesia rather than being gelded by a flying pocket knife or razor. I hope he does not have kids so he wont' pass this on to anyone. At that speed, that's just damn scary and I'm not afraid to grind things that way.

For a knife edge, this system does not generate that much heat during the short time to sharpen a blade with mass behind the edge. For a razor, they are too thin and at this speed would potentially ruin the hardness.

Seriously, do not do this the way the video shows it, not with a knife and definitely not with a razor. You cannot humanly move fast enough to avoid the injury. Think buffers too.

That post made me go back and watch the video, no definitely not sharpening with the blade going into the wheel, recipe for disaster but you answered my question on using the wheel for razors none the less

Only one question: what was the brown paper for?
Did I miss something?

So in case that knife catches and and guts him he won't ruin his shiny table with bloodspatter

I know a couple knifemakers who will not approach a machine like that without a chainmail apron. They have no problem showing you the scars so you would know why.

After further review including some careful review of the video and editing software to slow it down, the wheels are turning away from the operator, Not down toward the operator. That makes this tool operation exactly the same way I do it in my shop, except mine is turning toward the floor not the wall. It is possible to catch the point of a tool being sharpened and that makes for a very exciting moment. It hasn't happened to me for several years now (because of experience) and will probably happen the next time I turn it on (because of karma.)

On that basis, I apologize for saying anything about stupidity where it is not earned.

Safety issues with this type of equipment are still necessary.
