Welcome,
I would describe myself just as you have. New to fixed blades, with the some experience with sporting goods store knives. I just got a 5.1, and honestly didn't think I'd be comfortable with a knife that big. I am a woodworker, and make grips for pistols and knife handles, and wanted to get a good knife to make a set of scales for. Survive!, for a host of reasons (great knives, great reputation, good price point, fantastic values as a company... to name a few) was just the kind of knife I was looking for. I strictly bought the 5.1 as a project knife to showcase my grips, and am more and more thinking this knife will stay with me. Yes, it is large, but it is so well made and clearly a fantastic piece of hardware, I keep thinking of all the ways I want to use this thing. It is not too big, and I do think it would suit your purposes very well.
It would be too large for routine hunting duties, I'd say. But more knowledgeable people may disagree. But a knife with game processing and skinning tasks as the main purpose would be too small for most camp chores that the 5.1 will handle with ease. So depending on the tasks you are imagining, step up to the 5.1. I have no experience with it versus a 4.7, sorry, but I can offer the comparison to more conventional hunting knives. This thing is amazing and you will not be disappointed. Just my $.02.
