I'm in Athens, GA.
If you get down to Augusta, GA, Fire Side Outdoor Kitchens carries an excellent replacement for the original WG product.
I believe it is from their original source, good stuff. WG changed their source …
Spyderco Sharpmaker. Similar to other designs, but this one actually works very well. Very happy with it.
Another vote for the Sharpmaker. I tried various systems that held a stone at a fixed angle, but none of them work…
