I cut a very hot hard boiled egg and found a blood spot inside. Does that make the knife not kosher?
Question continued:
If yes, can I kasher the knife? How would I kasher it – it has a plastic handle? Its a knife that is usually used to cut onions and other sharp foods
Answer:
If it was a regular commercially produced egg, the knife remains kosher and there’s no need to kasher it.
