HORL 2 Walnut Rolling Knife Sharpener - Kitchen Knife Sharpener for Razor Sharp Edges - Diamond & Ceramic Knife Sharpening Kit - Professional Rolling Sharpener with 15° & 20° Angles - Made in Germany

Understandable regarding setup hassles. From what I have read if you want to go with a rolling sharpener then get the brand Horl, not a knockoff. They are on sale at your price point on Amazon currently. https://www.amazon.com/HORL-HO2-HORL2-NUT/dp/B08JYKN185
