What it does
- Guides your blade at the right angle so your knife gets sharp faster and stays sharp longer
- Four angle options fit pocket knives, kitchen knives, hunting knives, and more
- Sits still on your stone while you move your knife, so you keep steady pressure the whole time
- Helps you learn proper sharpening technique without years of practice
Sharp knives make cooking easier and safer. This sharpening aid guides your blade to the perfect angle every time, so you spend less time sharpening and more time using your knives.
The wedge sits on your whetstone and holds one angle steady. You pick from 14, 17, 20, or 25 degrees based on your knife type. Kitchen knives typically need 20 degrees; Asian blades work best at 14 or 17 degrees. Then you lay your knife on the wedge and stroke across the stone. The guide keeps your angle locked in, even if your hand drifts.
This tool turns whetstone sharpening from guesswork into a skill you can do right now. No fancy equipment needed, just your stone and this guide.
