Armor Piercing Weaponry

There should be a new type of super rare ore that could be from the end, or the deep dark, and this ore should be able to craft weapons that can pierce through armor. For example it shouldn't completely bypass armor, but it would be so that the armor would provide very little protection against it. The ore could be crafted into a sword, axe, or arrows to make armor piercing arrows. If in sword or axe form, it could do as much as a diamond sword or axe to make it balanced. Maybe even tools as well. I think this would be really useful because it would give those OP players in full Prot 4 Netherite something to fear. (It would still pierce through protection enchantments). It would really balance gameplay and give people a new equally powerful source of weaponry to go for. And it could maybe even be made into armor, or a new type of shield.
