You have an all-around good set-up. I definitely like the Master Hunter better than the SRK. I use knives alot and I just prefer drop point blades because of overall strength and utility. (Yes, and I've broken the other blade styles' weaker tips from time to time, but they were cheapie knives anyway) I am partial to a multi-tool though, but if it's a locking-blade SAK, I myself would consider keeping it. I'm clueless on the Victorinox Rucksack. Does it have pliers? I saw an SAK with some once. I second packing a lightweight folding saw, its well worth lugging. Toting the RSK EDC is a gimme for me.

Unless you need quick access to a blade when climbing or something, I think you are making the right decision on ditching the Becker Necker. I would have to wear gloves or wrap paracord around the handle before using it for any heavy duty work --- just the exposed tang on my old Buck Alpha Hunter 3 3/4" fixed blade raises blisters. I finally wrapped the handle on it with foam and Super 33+ to use for different things.
