I have a Case Folding Hunter. It's kind of a beast.
There's a lot of utility in the format. It's a little bigger than a Buck 110, as you can see here (
and here, too)
I also have a couple of Case Trappers. The format is pretty similar to the Folding Hunter above, except that the skinner blade is replaced by a spey blade and the clip point blade is more of a "toothpick" style.
The Trapper is smaller -- but not a lot smaller -- and considerably lighter. Whereas I could never pocket carry a Folding Hunter, I can easily pocket a Trapper. (If you think about it, the Folding Hunter is appropriate for large game, while something you'd call a "Trapper" would be aimed at somewhat smaller game animals.)
Having both blades pivot at the same end isn't necessarily my favorite format -- I kind of prefer the opposing blades of the Muskrat or Moose patterns -- you nonetheless get a very versatile knife with a general purpose clip blade and a blade that can be used for something more specialized (I use my spey for preparing food).
I like having two full-sized blades, whether they're opposed or pivot at one end.
The Trapper provides that.
(I wonder what a knife would look like with three full-length blades -- think of a Stockman, but with all the blades the same length. What would you even call one of those?)
