I found this episode especially amusing because I used to own one of the Chinese clevers he's making a replacement for, and they are awesome in exactly the opposite ways the knives he makes are awesome.
They're made out of thick, cheap, soft, stainless steel that means they go blunt in seconds but sharpen just as quickly and it is almost impossible to permanently damage them as they bend rather than break.
Conversely, his knives are light, will keep an edge for years, and cut through neatly anything - but if you damage it you'll be in for a world of work, and sharpening is a decent amount of effort and requires skill.
