I've got a decent collection of some pretty good knives. I like to keep them sharp. Some of the knives have modern knife steels (S90V, S35VN, CPM154, 3V, D2) that will hold an edge for a very long time but they can be difficult to sharpen. I've used a Lansky sharpening system for years and also have and use a Chef's Choice. They're both good sharpening systems but it seemed I needed more capability. I was having a time with a couple of knives that have very hard steel. Read a little about the Ken Onion Worksharp and decided to give it a try.
Wow, talk about a game changer. Sharpens any knife to shaving sharp in no time. This sharpener can handle serrated blades and also gut hooks.
Fully recommended.
