If I could offer just one piece of advice, it is this. If possible, find a Case knife dealer near you and hand pick your first one.
They make at least two different size Stockmans, some are serpentine and some are straight, some have rounded bolsters and others are square.
The color in the dyed bone, weather or not the blades rub, strength of the "pull" it takes to open, the "snap" (or lack thereof) when closing the blades, or any perceivable blade play are just A FEW of the things that can make or break a knife for some people more than others. You cant "see" these things on your computer's monitor.
There are more variances from knife to knife within a production run for these kind of knives than you might think, and I would hate for your first to be your last because of "luck of the draw" on an internet purchase.
You can find dealer locator on the Case corporate website:

)
However you shop for it, and whichever one you choose, I bet it wont be your last!
