I would have to say that if I were completely new to this expensive addiction, I would probably start out with one of the RRiders, a Colt, or something like that to try the patterns out. For less than $10, you can buy a knife to carry around and see how you like the feel in your pocket, test which blades you will actually use, and find out its utility value to you.
I have 3 - 4 nice trappers that I bought in CASE and other brands, but don't carry them. Haven't for years. I found 30 years ago I don't use any blade but the clip point. On the other hand, my CASE copperhead has been used so much the spine of the blade is starting to bend backwards where the large blade hits the spring. That is a lot of use! I keep a good working edge on the large blade, but a much finer, sharper edge on the smaller pen blade.
I love my two Soddie Jr. knives, but miss the smaller blade. I found that after spending a lot of dough on knives that I really like Canoes (large and small), Barlows, two bladed Jacks, Gunstocks, etc. After a few decades, it finally dawned on me that my preference of patterns for a traditional are limited to a pattern with one large blade, and one small.
That being said, I finally found the medium Stockman I have always wanted from Queen, I don't know what I would do without a large stockman, and of course, my Soddies.

You can spend a lot of money looking around and testing patterns out. I would go inexpensive to find my pattern and start saving for a real keeper once I found my way. Go to any store that sells knives, a gun show, or any place else you can handle a knife, and keep track of the ones you like to get started. If you decide you don't like those inexpensive starters, you can always gift them away, carry them when you travel, or let your brother in law use them. They have a place.
