Hello, I would like to know if a fleishig knife was used to cut warm eat and was immediately (mistakenly) used to cut bread that is dairy (it had cheese on it) what is the procedure with such a knife does one have to kasher it. It was used to cut onions but not in the same day.
Thank you for you time

Answer:
If the knife was already cold – which appears to be the case, because it was only used with “warm” meat and was presumably not hot a short time later – there is no problem with the knife. Make sure you wash it off well, and also cut off the part of the bread that came into contact with the knife.
Best wishes.
