Plate mail isn't hardend steel plate. I can't think of a single armor of the middle ages that was better on the Rockwell scale than weapons of the same technology level of metallurgy and smithing. There are plenty of actual videos and pictures of weapons piercing plate armor. This shouldn't even be up for debate.
Actually the latter ones were hardened, even "bulletproof". And no, even if they were technically of lower hardness then the blade, you still can't generate enough force to cut through them.
