I bought two of these a while back... just because. Both are very nicely made, great walk/talk.. they came with a very nice edge. I'm very pleased with them, and would be, even if they were double the price.
I started a little bit of whittling with one of them yesterday after touching up the edge and finishing on a smooth ceramic stone for polish. It worked as well as the other knife I had been using (on spanish cedar) and after about 20 minutes of shaving chips off it, it was still sharp enough to continue using. Apparently their version of stainless is "ok"... certainly not M390 great, but usable...
If I could find a GEC viper I could afford, I'd likely buy it. I'm still thinking about Mike's viper, and will likely buy one, but have committed funds to other projects at the moment..
