Pros: Durability, Ease of Use, Effectiveness, Overall Quality
Easy to use and it works. . . .
Like the finishing hone I bought one of these over 15 years ago and just now needing to replace after weekly use on multiple knives. Like the finishing hone these work great as prevt. maint. for your knife, when the edge gets just a little dull make a few strokes on each steel, run it over the finishing hone and it's razor sharp. This will make knives that are fairly sharp - extremely sharp. I'd typically run my carry knives over these once a week or so with light use and hit the finishing hone almost every day or with every use. This greatly reduces the need for a traditional sharpening and only takes a few seconds to keep your edge in great shape.
