i got 4x80%+ steaks from a moose last time i got one
skinned and quaterd with a pristine combat kinfe
what knifes were you using? m91 or sks bajonets? i don't know if they are actually sharp because you usually use them for stabbing enemys, not slicing

We have used all knifes in the game. At pristine.

My pig I caught and gutted gave me 30-60% meat with a damaged knife

as experimental servers are hardly spawning enough food to stay alive atm (sometimes not even that), i had to go hunting with a badly damaged cooking knife and got 10% or less (haven't seen -1%, but at least 0%) from every animal i killed

i had a cooking knife in a prior life (think it was worn or pristine) wich gave me 80% or more

this mechanics seem to be a bit stange to me, because even if your knife is not sharp, you should be able to get all the meat from an animal.
it's nonsense, that you can kill and gut a cow, but still have to starve, because you get only tiny bits of meat... if an animal has, for example, 10kg of meat, but you cant get it off in 20 bigger pieces (500g each), but in 100 tiny bits (100g each), the meat is not lost, just distributed differently

i could imagine it for the game like this:
a cow has 750"%" meat. you multiply with a value in order to reduce the ammunt of meat and distribute it among the pices of meat (with depends on the tool factor (8/tool))(and 100%*tool as maximum)
the reduction of meat should not be to high, as you would loose not to much meat imo. i am no butcher or hunter, so i can't tell any realistic values

tool factors could be like:

knife:
pristine 0.9-1
worn 0.8-0.9
damaged 0.7-0.8
badly damaged 0.6-0.7

machete:
pristine 0.75-0.85
worn 0.6-0.75
damaged 0.5-0.6
badly damaged 0.4-0.5

axe (yes it should be possible to gather meat from an animal with an axe, the pelt/leather could still be ruined):
pristine 0.45-0.5
worn 0.4-0.45
damaged 0.35-0.4
badly damaged 0.3-0.35

i know this post is rather a suggestion, than a bug report, but it seems to me, like this is a intentional (maybe not the -1% or 0% pieces) , so i wrote down a way it might work better

Hat this problem also before with a machete

Hello madbawls and others,
this is something that we believe has been fixed internally and should also be fixed in the next Steam update.
Please create a new ticket if the issue persists.
Thank you,
Andy
