At least all the blades are different...
But yeah, I'm with you on this one. The only congress I have so far is a 3.5" Steel Warrior, which I bought because the blade selection is the same as Case's, with 4 different blades. I love the variety, but couldn't see needing any more, except perhaps for a hawkbill/pruning blade, but the coping blade is close enough. Any larger, and that'd just be way too much knife, at least for me. The Colt (which looks to be the same manufacture as the Rough Rider) is 3 7/8" and 4 backsprings wide. That's a brick in your pocket, and frankly, despite being different blade shapes, the usefulness of some are fairly redundant. A spay blade and a pen blade? Large clip and small clip? Small clip and pen blade? Large clip and spear point? The only one with a true uniqueness is the sheepsfoot. I've made no secret of my dislike of redundancy in blades, even though I understand the appeal of duplicate blades so you can go longer between sharpenings. The apparent appeal of having 6 different blades is choice and variety for the perfect blade for the specific task at hand. But on this particular knife, apart from the sheepsfoot, there's nothing that one blade on this knife does far better than at least one other.
Honestly, if I were to choose any number of blades from the 6 on the Colt/RR, I would chose the large clip, the pen, and the sheepsfoot, and no more. And that'd just be a regular 3 blade stockman.
Just my opinion.
