Assess, sharpen and care for every kitchen knife offline
Keen Angle is a practical offline bench companion for people who want dependable kitchen knives without guesswork. Keep a personal knife roll with steel, purpose, target bevel angle, edge-health score and last-care date. Run a quick four-part edge check using paper, tomato skin, reflected light and damage inspection. Keen Angle turns the result into a clear health score and a useful next step. When it is time to work, choose a knife and follow a focused whetstone, ceramic rod or strop session. Each guide explains angle, pressure, burr formation, refinement and safe testing in plain English. Completed work becomes a local care history with before-and-after scores, method and notes. A built-in reference library covers bevel geometry, abrasive choice, stone flattening, curved tips, burr removal, edge tests, cleaning and safe storage. Adjust each knife's preferred angle as you learn how it performs. Everything works offline. Knife records, checks, progress and sharpening history remain stored on your device, ready at the counter or workshop bench.
