A Model #7 is "named" The "Fisherman-Hunter". It certainly lives up to that name..."BUT"...(There comes that word again) the #6 grind makes the knife far better suited for the "fish" side of the name. You can lay the blade down (flatter) and skin fish easier, faster and closer.
It also works better in the kitchen. That's why a Model #6-4 1/2", "Steak" knife is so named and chosen by the Randall shop to accompany the #6-9", Carving set. In short, at least for "me", ordering your Model #7-4 1/2" or 5" with a #6 grind just makes more sense...for it's "intended" purpose.
If you are looking for more of an "all-around" knife (I'm not ever sure what that means) then the standard grind "Fisherman'Hunter" might be the better choice. It has a little more "backbone" and is the perfect companion to it's big brother, The Model #3! Hope this "sorta" answers your question.
