The only must haves IMO are:
1. A locking folder
2. A mid-sized fixed blade (4 1/2-7 inches in blade length)
3. A big, stout fixed blade (9 inches or longer blade length and at least3/16 thick)
4. A hatchet, axe, or tomahawk
As far as specifics on brand names and features go, that is entirely personal opinion; go with what works for you.
