How to Turn Bathroom Tiles & Sandpaper into One Heck of a Knife Sharpening Kit
A knife doesn't do much good if it isn't sharp. Ever tried to cut up vegetables for dinner with a dull blade? You're more likely to cut yourself than the onion.
Most easy-to-use sharpeners aren't good for your knives, and a good sharpening stone can be pretty pricey. That's why Instructables user Quad89 decided to make a DIY version with cheap and easy to find materials.
Quad89 used a couple of smooth bathroom tiles as the base. He cleaned them off with acetone, then used a spray adhesive to attach different grades of high-grit sandpaper to each tile. He let them cure for a few hours with a weight on top to make sure the sandpaper stuck as flat as possible.
You can replace the sandpaper if it wears out by peeling it off and using acetone to strip off the adhesive. Quad89 also recommends adding little rubber feet on the bottoms of the tiles to keep them from slipping and prevent them from getting damaged when stacked.
