This clip starts with the image of a rusty knife that looks like it has no chance of regaining its former glory and shine. But thanks to an incredibly skilled Japanese sharpening master, the knife looked brand new in the end. The Japanese art of sharpening knives is known worldwide, but I never would have thought that looking somebody sharp a knife can be so eye-pleasing. This is definitely something you need to see to believe. You have to see how the knives looks once the sharpening master is done with it. His technique is impeccable.
