3V is definitely the way to go for a knife that is going to see impact use, if you are willing to, e.g., invest in diamond stones and/or good waterstones, to sharpen your knives.
O1 is sort of a default easy steel to grind and heat treat, forgiving steel, and it's reasonably tough. But as is just a general truth, any steel that is "easy" to sharpen by definition must be easier to dull also, with slicing / abrasive cutting. CPM 3V is a much higher performance steel in all regards (toughness, abrasive wear resistance/edge holding, better resistance to corrosion).
For a camp knife, anything short of a big chopper or machete, 3V is such a good default choice in today's world.
Personally, I wouldn't pay big bucks for a Camp Knife in O1 nowadays, when 3V is around. And there are other steels that are rising in contention, all with various pros/cons ... CPM Cruwear, CPM 4V, Vanadis 4.
And I do eat my own cooking... just acquired this finely made custom shop Camp Knife in 3V:
