Sharpen your knives, scissors and garden tools

Buying grindstones for sharpening knives and scissors
Albert Haan from Repair Café Zwolle-Assendorp (the Netherlands) always brings his own sharpening equipment. Sharpening knives and scissors is a hobby that got out of hand for him, and in the meantime, he has started his own business. “The Repair Café in Assendorp is located in a community centre, which also has a small restaurant”, says Albert. “At one point, the cook was complaining about his blunt knives. Then I thought: you know what, next time I’ll bring my sharpening stones. Of course, the visitors saw that, and so I started sharpening more knives and scissors.”
Albert is not a fan of using knife sharpeners where you must run the knife through. According to him, they often cause a knife to be sharpened unevenly. “You often sharpen the first part the most because there you unintentionally press the hardest. That means your knife is sharpest at the handle and the least sharp at the tip.”
Knife sharpening tips
Albert recommends Japanese whetstones instead. These are rectangular blocks grinding stone. “Many people know them. They are grey and light grey. You can buy them at the hardware store and you can get your knives pretty sharp with them.” With these sharpening stones, it’s vital to always sharpen the knife at the same angle. “You have to keep the angle constant and go over the stone with it. If you start twisting your knife, you’ll never get it sharp.”
Even century-old knives can be sharpened. Albert: “One day, a man came to our Repair Café with a very old butcher’s knife. It was perhaps a hundred years old and had always been in the family. He had never dared taking it to the sharpener because he was worried they’d mess it up. But, in the Repair Café, he had seen me working several times. It gave him the confidence to bring his knife. So, I sharpened that knife, which before hadn’t cut for years. He was thrilled. Not necessarily because of the knife, but mainly because of its family history.”
