Knife sharpening can sometimes be tricky, but the HORL® sharpeners make it super easy and a real pleasure for everyone. No prior knowledge or trying around for the right angle needed! While the grinding disc rolls gently back and forth along the blade, the knife stays in place by the Magnetic-Angle Support. For even more culinary delights in the kitchen. #horl1993 #sharpener #knifesharpening #rollingsharpener #rollingknifesharpener HORL® Online Shop Europe https://www.horl.com/us/en HORL® Online Shop USA https://www.horl.com/us/en
