For three days, I usually don't limit myself, since I don't have that much weight in food with me, compared to say a 7-10 day trip. My pack is about 60-70 litres, and very good at bearing weight (Gregory Reality), so a pound or two extra for knives is no big deal.
I usually take either my big knife of choice or my Large forest axe, or sometimes both. These days my large knife is a 15 yr old Recon Scout or a custom Howard camp knife.
For the smaller fare, I take:
-one of my Bill Buxton hunters, a customized CS Master Hunter, Dozier PGK,or a F1,
-BRK&T Mini Canadian or WM1 (or both)
-one of the larger SAK's (can't remember the model name) and a Rucksak.
plus I always have my Raven (from Ragnar), and a mora.
Tarmix101, if I had the combo that you originally posted, I would probably carry it. Love that bushcraft-style knife. Is that a sharpening rod in the sheath instead of a firesteel?
In reality I use the Recon Scout for nearly everything, just because I like it, and since it was my first serious knife, there is sentimental value. Plus it has the best edge profile on any large knife I have seen. And much better than most other RS examples I have seen or used.
I have gotten rid of most of my bigger knives, as I just don't use them much. Maybe a new chopper is what I need....
