Just received the Boss Jack. Seems like a wee bit of a convex grind on the edge there, but it didn't come very sharp at all. Also have the Fallkniven A1 and find the two of them to be almost exactly the same size and weight. I'm finding the grip on the BJ to be a bit thin, whereas the A1's is just perfect for my small/medium hands. Will also be getting the Fehrman Shadow Scout, then will do a much more comprehensive comparison. Should be interesting. Btw, the fit and finish of the Boss Jack is quite excellent.
