I get a ton of questions as to how to sharpen and maintain a knife with a convex edge. Since a picture is worth 1000 words, I figure a video would be worth a ton more! We had a contest to see who could make the best instructional video on sharpening and this is the winner. The entire video is about 30 minutes long. I recommend watching the whole thing—it is the very best explanation of sharpening I have ever seen. If you only watch one chapter, watch the one on using the KnivesShipFree leather hone. It covers everything very quickly. Enjoy.
