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.
What kind of people would write collect and review multitools? Quite simple really- we are designers and do-ers, outdoors types and indoor types, mechanics, doctors, problem solvers and problem makers. As such, we have, as a world spanning community, put every type, size and version of multitool, multifunction knife, pocket knife and all related products to every test we could manage in as many places and environments as there are.
