About this app

Angle of Knife is a knife sharpening app that turns your phone into a real angle meter. Lay it on the blade, get the exact sharpening angle, keep every knife tracked — no guesswork, no ruined edges.

Whether you sharpen on a whetstone by hand, use a guided rod, or run a sharpening machine, Angle of Knife keeps every knife sharpening angle honest.

KEY FEATURES

• Angle meter — live knife sharpening angle, updated in real time
• Whetstone guide — audio beep when your blade hits the target angle
• Works for any tool — whetstone, guided rod, belt sharpener, bench grinder
• Blade log — save every knife with its angle, steel, photo, and full sharpening history
• Presets for chef's knife, pocket knife, hunting knife, kitchen utility knife, fruit & vegetable knife, axe, and more
• 8 languages, metric and imperial

WHO IT'S FOR

• Home cooks who want a sharp knife without paying for pro sharpening
• Whetstone learners tired of guessing the blade angle
• Hunters, campers, and EDC carriers who sharpen in the field
• Woodworkers, chefs, and hobbyists who care about repeatable results
• Anyone who has ever asked "is this the right sharpening angle?"

HOW IT WORKS

1. Pick your knife from the list — or add your own with a photo
2. Set the target sharpening angle (or use the preset for your knife type)
3. Lay the phone flat on the blade and start sharpening
4. The angle meter beeps and turns green when you hit the target angle
5. Every sharpening session is saved to your blade log

WHY IT WINS

Whetstone sharpening is a skill, not a mystery. The moment you can see the blade angle, everything clicks. Angle of Knife gives you that view — cheap, silent, always in your pocket. No more ruined edges, no more expensive sharpening services, no more guessing.

PRIVACY

Sharpen smart. Sharpen often. Sharpen right.

Ratings and reviews

Very limited use so far, but for what it's designed to do so far it's spot on! Easy to zero. Able to store data for specific knives. Simple, easy to use.

I wish it was in English. I can't figure out how to use this tool to sharpen my knifes. I'd give it more stars if that was the case.

Terrible and useless
