T'Challa claws are supposed to be Anti-Metal but this is all was seem to be depicted in a very unimaginative/boring ways like a downgraded tool from wolverine toolbox/power-set
what would really make the "Anti-Metal" in "Anti-Metal claws" mean something special/unique and differentiate T'Challa claws from all the other character with claws,knives,swords
would be to have it depicted/look like a melting/dissolving effect on metal's when T'Challa use's his claws instead of the cutting/slashing effect we usually always see but keep the cutting/slashing effect for other object/material's that are not metal based
think about how cool would it have been in the Black Panther movie to see something like T'Challa having to get passed something like a metal vault door that's 2 or 4 feet thick to save someone or get something and he pop out his one inch claws and the audience is thinking to themselves sarcastically like "YEAH RIGHT" and then T'Challa start scooping out liquefied metal hand over hand from the vault door as easy as scooping up a handful of snow or sand and in a matter of seconds there's a massive human sized hole in the vault door and the audience is now like " WOW HOLY SH*T" didn't see that happening like that
that what makes the "Anti-Metal claws" melting/dissolving effect so much better then the cutting/slashing effect is that it would not only look unique but it would let T'Challa do stuff he would never be able to do with just the cutting/slashing effect we always get from his claws and it is almost like an upgraded tool from wolverine toolbox/power-set
