I have a GB, but haven't had much of a chance to really work with it, being winter and all. However, someone asked the right question. Which Busse?
The GB is one hell of a knife. Very well made. Great balance. It's got a very heafty blade. Anyone breaks this knife, you can bet they were either trying to save their lives, or simply doing something no one should do with a knife!
Mine came sharp, but not as sharp as my Mountaineer II. The GB does have a thicker blade, though. A little work on my Sharpmaker brought it to "paper slicing" sharp. Not bad for a blade as big and thick as the GB. The handle is comfortable, too. I would prefer no serrations. 1" of serrations on a 7" blade I can live with and might actually come in handy.
I also own 2 Busse's, a 3/16" SJ and 1/4" NO. It is heaftier than the former, but, not much less than the latter. My SJ has a convex edge and cuts/slices really good. The GB cuts/slices better than my NO. Yet, might loose a little to my SJ. Not much, though.
Different knives. Different uses. Either way you look at it, the GB it a great knife, which no one would be regretful to own.
