The Polished Blackstone Pressure Plate is a Redstone component that activates when a player or mob steps on it. It functions identically to a Stone Pressure Plate but is made from Polished Blackstone. A Polished Blackstone Pressure Plate is crafted using 2 Polished Blackstone in a 3×3 crafting grid. It does not generate naturally and must be crafted by the player.

When placed, a Polished Blackstone Pressure Plate sends a Redstone signal while a player or mob is standing on it. The signal stops when the entity moves off. Unlike wooden pressure plates, a Polished Blackstone Pressure Plate cannot be activated by items, arrows, or projectiles, making it more suitable for controlled activation.

A Polished Blackstone Pressure Plate can be broken instantly by hand or with any tool. Unlike a Heavy Weighted Pressure Plate, it always emits a full Redstone signal when activated, making it useful for consistent Redstone triggers.
