So...
For me, the answer/s to this question is surely influenced by the intended use. A $100 budget is obviously limiting so I'd think we'd want to understand what we'd want these knives to accomplish.
Also, I will not shop at Walmart so for me, those prices are irrelevant.
And, assuming sharpening is already taken care of, then here's some of my thoughts...
1)
MOST VERSATILE:
- Buck 110, ~$46USD: Beast of a knife. Whether it is cutting up an apple at work or field dressing an animal, the 110 will do it all. It can be bulky on a belt and maybe not ideal for all situations, but the standard 110 offers tremendous gives-and-takes. This is an awesome "compromise" blade.
- Victorinox Rambler, ~$26USD: I hate including the Rambler or Classic as knives as for me they are just tools and I'd love them even without a blade, but, of course, technically they are knives. So, here I would pair the 110 with a Rambler.
- The next one is tough, but, I think here I'm going to put a Buck 425, ~$15USD. The Rambler's blade is just too small for much and it might not always be convenient to use or carry the 110. And I know from a lot experience that the 425 punches WAY above it's weight. It's an awesome knife that could only be better if it was offered in orange.
I know I'm leaving $13 on the table here but I think this is a great compromise-setup for most anyone.
2)
OUTDOORS ORIENTED:
- Man, I really want to put some Buck PakLites here but I don't think they qualify as "traditional" so I'm leaving them out. Mora's are obviously an attractive and excellent option here but I reckon I'd have to go with a Buck 102 Woodsman, ~$53USD. Great for fish to fowl and adequate for larger game and camp chores. One should be conscious of the potential for the handle to be a bit slick on larger, bloodier game, but it can get the job done. I'm not in love with Buck's modern sheaths but they will do. I could biased here as this was the first knife I ever bought with my own money, more than 40yrs ago, and my daughter totes it around these days.
- I'm going to pair this with a SAK Super Tinker, ~$32USD. Great tool selection for the outdoors or just general use and still easy to carry.
Fifteen bucks on the table for however you want to spend it.

GENERAL EDC:
So many options here that I don't know that there's much benefit in giving my opinion. I think a SAK Classic or Rambler is an absolute must. I prefer the Rambler and unless circumstances preclude it, I won't be without one. I use mine every single day, usually multiple times a day. From there it's what's you like. I think a Case Mini Copperlock, Trapper, and Mini Trapper are all excellent options. If a beefier knife were desired then a Copperlock or Tribal Lock.
Just my rambling thoughts. Tons of options out there for sure.
