The person that made that video sent me some razor knives a year ago. He is big into knives. I kept wanting to make a video about razor knife but never got around to it. He makes some cool videos.

yeah he has several videos where he does an 'autopsy' on various fireworks shells/cakes/etc . to see how much powder is inside and so on .
quite a tinkerer .
