Welcome to the forums..... lots of good questions, expect lots of good answers!!!
You might want to give us idea of what your price range is, there are good knives in every price "bracket", obviously there are better knives at higher prices, however their benefits may not be worth price increase.
If your husband is hunter, then Dozier makes EXCELLENT fix blade knives which also are excellent general use. These run in mid to high $100 range.
But also there are good chaper price fix blade hunters below $100, two well-regarded knives on this forum are Cold Steel Master Hunter (in non-stainless carbon steel) and Fallkniven F1 (in VG-10 steel, a very good "stainless" steel).
Of course, stainless vs. non-stainless depends on your husband's preference, if he looks after his tools carefully then carbon steel would be fine (usually slightly cheaper, also usually better edge holding and toughness but not always), otherwise stainless is way to go.
Axes are different story, if you know your husband likes axes then post a separate question in the Axes forum here. They are exccellent tools but require even more skill, safety and care than knives. I would keep away from axes unless you know your husband is skilled in using one.
Machetes- many varieties available, very good ones can be found for cheap. Others with more experience will chime in.
Welcome again, and happy "hunting" for a good knife, axe, machete..........!
