It seems like this entire channel’s Thing is making kitchen knives out of improbable substances. See also the clingfilm knifechocolate candy knife, and pasta knife (which is then cooked and eaten… and then the plate turned into another knife) for example. The fact that most of these knives end up being better than my actual kitchen knives is… probably a hint I should get my knives professionally sharpened.
