First things first, you'll need to invest in some high-quality whetstones – and trust me, these aren't your grandma's magic erasers! Japanese whetstones are made from silica and aluminum oxide, which make them the perfect combination for sharpening even the dullest of knives. Just don't expect to use them to polish your shoes, okay?
The type of steel used in Japanese knives is also an essential factor, with high-carbon steel being the preferred choice for its durability and sharpness. But don't just take my word for it – after all, who needs surgical precision when you can have a dull knife that's only good for buttering toast?
