Found my answer!
One thing you need to know is that pierce, stab and slashing are not some unique hax/durability negating abilities.
It's just a matter of pressure. Under an equal force, if it's on a smaller surface area, the pressure will be greater and thus can lead to rupture in that region.
At high-level, P=F/A, and if a guy is withstanding 100000N at 100cm^2 contact, he is also very likely to withstand 1000N at 1cm^2 contact area. Amp that by a gazillion times and that's what happens in Edens zero
Anyway, since you asked for showings, base Shiki tanked Nero's dice. They pierced straight through Jaguar, Ziggy, Ground, spaceships, etc.. without obstruction but were bounced back by Shiki's head.
Same Ziggy tanked Elsie's slashes without having his armor pierced, heck, even Valkyrie who specializes in offense tanked Brigandine's Axe cutting
Even back when Shiki was more or less comparable to Kris, he tanked his "Windstorm Slash", it diced up the road back on Bluegarden
