What has better gather for animals

I keep hearing people say the bone knife does better than the metal hatchet when skinning animals, is that true?

I believe that their gather rate is the same, but bone knife swings faster.

True. Most people just use metal hatchet after you get it to save inventory space.

But before you get the bp for it, bone knife is way better than stone hatchet for gathering.

Bone Knife = Metal Hatchet

If you dont have the Metal Hatchet use a bone Knife.
Their should be an normal knife that gives even more in my Oppinion
