Ansen Tools Grit Sharp AS-402 6-Inch Double-Sided Continuous Diamond Sharpener Coarse/Fine with Non-Skid Rubber Base

This is the fastest sharpening tool I've ever used. Previously I relied on the work sharp belt sanding machine along with Spyderco ceramic stones to sharpen knives. The Ansen diamond tool is faster and gives a sharper edge on knives I had previously sharpened. I followed the Ansen diamond sharpening with a few strokes on a homemade strop with green compound. The only problem I had with this tool is it did not fit in the plastic case. A little sanding with 120 grit on each side made the tool fit snugly in the plastic case. I am a knifemaker and have used many sharpening systems over the years. This one is the best yet and is light enough I can include it in my wood carving kit or bushcrafting pack.

Does a good job. The "fine" side is a little to course.

Great price! I love that it has two different types of diamonds. With a few passes my knives are very sharp. I have other sharpening systems, none of which measure up to overall effectiveness and ease of use.
