Angle of Knife: Sharpening

Lay your phone flat on the blade and see the exact sharpening angle. No guessing, no ruined edges. Angle of Knife turns the phone in your pocket into a sharpening angle meter. Set the angle you want, start sharpening, and the app beeps the moment the blade sits right. Works on a whetstone, in a guided jig, or on a machine. No stone? Use a mug Nothing to sharpen with at all? The app walks you through it step by step on the bottom of a ceramic mug: which mug works, what angle to hold, how to move the blade, how long per side and how to strip the burr at the end. It gets a straight edge cutting again when there's nothing else at hand — serrated and bread knives need a different tool. No jig? Use the calculator Enter the blade width and the angle you're after. The app shows the gap under the spine in millimetres — and how many coins to stack to hold it. That's the whole setup.
