I got my 56 in Appaloosa the other day and haven't really had a chance to formulate some thoughts on it yet...
I think I prefer the 2 blade variant in terms of its usability and utility but this single blade variant is classy, but rustic in its own special way. I've become quite taken with the Appaloosa Bone, I never dreamed that I would actually like it. But it is a material full of character and beauty. Couple that with the other aesthetic upgrades such as lined and dimpled bolsters, a long match strike pull, and the classic Federal shield and you have a truly elegant knife with a bit of a cowboy edge to it.
Aside from the slimness of the knife being slightly off putting, the match strike pull is the only other thing that gives me a bit of a problem in terms of its accessibility. I am not sure if the groove is narrower or shallower than a typical long pull but my thumb nail tends to not want to find a good purchase in there. So I have to make a concerted effort to make sure my nail is firmly in place before opening.
Other than those minor complaints, the knife is a real beauty and I am looking forward to having it be a part of the ever growing collection.
