I held an EVO at a shop in CT. I really liked how it looked in pictures...in person, I didn't like it much. It was chisel ground and seemed unfinished overall. I held a Beck WSK at the same time (and have used one). It was a huge difference -- night and day. If Roger Linger's work is anything like Beck's (and it looks to be), then go with Linger any day of the week. The EVO is okay, but the Linger version of the knife seems like it'll give you much greater utility (i.e. saw blade and edge geometry overall).
Now, the EVO I held might have been an early one, or an unfinished one that somehow got out, I don't know. That's how rough it looked and felt. The example I held just did not look like what I had seen in pics. So, it may not have been a good one to use to compare. Before I come to any final conclusions on the EVO, I'd like to check one out that isn;t chisel ground and is more finished. But based on what I experienced, then go with Beck or Linger anyday.
