As a trapper, hunter, and fisherman for food in my youth, and as a woods runner and fisherman in my retirement, I've known the value of sharp woodland tools for over 60 years. I've spent a lifetime working with natural stone, diamond plate, and ceramic sharpeners and sharpening systems of all shapes and sizes. My one fundamental (and admittedly personal) preference was to master the use of tools that did NOT require electical power to make them work. The Work Sharp Field Sharpener has been a favored tool both in the field and in my garage for years now.
The Elite assembly though, with the added fine and extra-fine diamond plates, takes the value of this resource / tool to an outstanding level.
Until I stumbled upon the Elite model's advertising, whether I was in the garage prepping for the next camp or when I was afield, the use of the standard Field Sharpener has been followed by polishing the tool edges with fine and extra fine ceramic (dog bone style) ceramics having a flat surface. The flat surface of the dog bone tool allowed me to polish fine blade edges consistently in a way that the round ceramic on the Field Sharpener did not. (My limiting skills and habits are stressed here more than commenting on the tool.)
With the Elite model of the Field Sharpener I no longer need the dog bone ceramic. The fine or extra-fine plates snap into place magnetically, often replacing the course diamond plate for weeks at a time. The resulting "near mirror" polish of my toughest steels (D2, S90V, S45vn, 3V) is gained with far greater ease than with the standard Work Sharp plates plus ceramic rods.
When "skinning sharp" edges weren't needed, like on my primary wood processing hackers and axes (Ontario's SP-8 in the photo for example), I'd often skip the polishing step. Now, with the Elite model, I refine those edges as well simply because it is an "oh, never mind" level of additional effort!
In closing, I ordered the Elite Field sharpener directly from worksharptools.com, in addition to a few spare coarse and medium plates for my varous tool kits having Work Sharp's sharpeners included. I could not have received better service from any vendor. The tools received and the service in purchasing those tools were outstanding!
