The Japanese have a knack for doing things in such a way that are just satisfying to watch. And this video will make you go “ahh”: a Japanese knife-sharpening master turning a rusted kitchen knife into what could pass for a brand-new tool. Prepare to feel like the air around you tastes a little sweeter as you watch the rust melt away with his delicate yet masterful technique.

Apparently sharpening things is this guy’s passion, since his YouTube channel is filled with other videos of him sharpening and cleaning blades. If you’re feeling a little rusty yourself, then check it out; it might just make you feel bright and shiny again.
