Buddylee, there is the fun factor and the cool factor and the beautifull factor that are present when people are choosing a knife for edc or for carry in non urban settings.
But when it comes to it, if you really want practical picks, its not too complex. For me a swiss army one hand trekker, to do all the craft work in the woods. It is also my urban edc as well. I carry it in the watch pocket of my jeans.
Then there is my Becker Necker, it is always with me in the woods, I've carried it since the day it came on the market, it gets used alot less, it comes out when there is a messy job to do, like field dressing a deer, or when there is a slightly more strenuous job to do, an example: opened a coconut with it the other day and yes some prying was involved. No problem for it all. But I you cant do that with your SAK.( although you could cut a stick and sharpen it with your SAK and then jam the coconut into it and pry it open with the SAK, so that is a very important point here). What is so special for me about the Becker Necker, it is a very strong fixed blade that fills a utility niche that a folding blade cannot. It is flat and light, so it is very easy to carry. It is skeletal so it is very easy to clean.
Finally if I know Im staying out over night my little tiny hatchet goes onto my belt. And a hatchet makes all those monster chopping Busse knives and Kukuris look a little silly in my eyes. It takes care of the only remaining niche.
And that is utility. If you need a fix of cool or beautiful or nostalgic you might need to look somewhere else.
