I mean...
I feel like that was very situational, was more like the plot forced Zoro to poke in that moment coz Oda was gonna have King explode.
Poke -> Explode
I mean outside that one scence I'll be shocked if there's more.
Surely I'm not tripping right? lol Zoro never really uses stabs in his fighting style.
If you can show me one named stabbed move I will take my L on this

In hindsight given the above panel, this poke also seems situational so Oda's putting focus on Sommer's dodging a bullet with Zoro just barely missing his heart
