Hi,lets say i have a blade in very bad shape,extremely rusted,so my question is:would it be better to leave it like that,or take out the rust by force? I don't care about looks,i could always take it to a polisher someday,but i want to get rid of rust to prevent it from spreading,what do you recommend me to do? How could i start the proccess? Is there any way to remove the rust without ussing abrassive tools? I heard somewhere that wrapping the sword with a cloth with some oil and leaving it rest for a few days will weaken the rust so it could be removed,does that work?
The picture attached is taken from the internet,my blade shape is similar to that one's
