I got a Ken Onion Worksharp recently and I finally found a quick and easy way to keep all of my tools sharp .
I have used it on every knife in the house , a machete , a hatchet , and my lawnmower blades .
The convex edge seems to last longer than a beveled edge , and slicing is much easier .
I'm push cutting things like never before .
Although the KO WorkSharp is a bit pricey , I think it was money well spent .
