I tend to cover a lot of sharp things but rarely talk about things made to keep them sharp. On social media I've been bombarded by advertisements for a sharpening device by Tumblerware called a rolling knife sharpener. I thought it seemed strange, maybe even gimmicky compared to other systems I've used in the past. I started reading the comments in these posts to see what people thought. Mixed in with the comments was folks pointing out that this sharpener was a copycat, and they stole the ideal from a company called Horl.
Otmar Horl and his son Timo launched the first Horl sharpener in 2016 and in 2020 launched the Horl 2 collection. This collection includes accessories like additional stones, and a leather strop for refining the edge. The Horl rolling sharpening system consists of two parts, an angle guide that holds the blade in place for sharpening, and a double-sided cylinder that's rolled back and forth to hone the edge. The Horl 2 system has a diamond disc on one side and a ceramic disc on the other. The diamond disc is designed to fix your edge, while the ceramic one helps further refine the edge.
