What sword can cut or even pierce through Stonfist's crab claws and more importantly its shell?

Disclaimer: This was supposed to be a video months ago where I did this hunt for the first time solo but the original footage of this hunt was lost along with my previous PC on 04/29/2023. I tried to replicate the build I used for the first hunt against this EX monster....
