buyer5207,
You may have already gotten the information that you need.
If not, it would be helpful to know some things about your travel plans.
-How many consecutive days of backpacking are you planning?
-How far are you planning to travel both each day and in total?
-Where and what time(s) of year are you going to be traveling?
I probably missed something. If I did, someone please chime in.
This is what I was thinking. I've done simple trail hikes to see a particular site and I've done hikes to remote locations for fishing. Sometimes, I'll get out and just hike in a 6-8 miles to set up a base camp and practice bushcraft or other skills with my son. It really depends on the distance, duration, terrain, time of year/season and what activities you plan on doing.
I will always have a folder and a fixed blade when hiking, even day hiking. Most times, I'll have either a SAK (Rucksack or Outrider) or my Swiss Spirit multi-tool. Even when backpacking, I really like and use a folding saw (Kershaw/Bahco or Silky are my top choices) quite often. For most seasons, I'll pack along my BRKT Golok if I plan to do a lot of wood work or feel the need to batten. It's not the best if used as a machete, but will still do a good job if I'm going to an area where I expect I'll have to clear out a camp site or make a trail to a lake or water hole.
I often carry more knives than I need, but if I'm going on a distance hike (which I haven't done this year), I really scale down and will take a very small fixed blade (like the Fallkniven WM1) and SAK. This is especially true if I'm using a stove and sticking to the trail, yet weight is a premium (although I'll still end up packing a "useless" Glock 23 or Bulldog .44 SPL

).
To put it more simply; I carry more than I probably need but exactly what I want

If you catching me bitching about the weight on my back, then Im carrying too many blades, tools and toys! Honestly, its really about your hobbies in the backwoods, on the trails and what the goal of the hike really is. Ive known some backpackers to be comfortable with just a small SAK and Ive known some comfortable with a Khukuri
balance your need with your wants and know the consequences of the extra weight or limitations of your choice.
