Sharpening master turns rusted blade back into brand new knife

RocketNews 24 (by Scott Wilson):

The Japanese have a knack for doing things in such a way that are just satisfying to watch. Check out this video of a Japanese knife-sharpening master turning a rusted kitchen knife into what could pass for a brand new tool.

Watch how this master craftsman turns something that looks like an object you’d find in a decaying cabin in Fallout 4 into something you’d be happy to see a sushi chef slicing and dicing your dinner with.
