Right, both Cutters.
It’s been fine. Unlike AW, Blades specifically says its fine to have more of the same playbook. It’s been fun for us to find ways to differentiate them in system and in fiction: Hammer has 3 Melee and has intentionally developed broad skills and started with the move that lets him heal faster, while Sickle started with 3 Command and the move that gives her more command dice when the target is scared.
So: One is tough and steps in to take damage, while also being good at resistance. The other is great at giving orders.
So, in fiction: Sickle was trained to be a general, Hammer to be her guard. Mom viewed him as expendable.
