Blue Prince: Sledge Hammer Guide

Image Credits: Dogubomb, Blue Prince

The Sledge Hammer is one of the most useful tools in Blue Prince, especially for players looking to save Keys or gain access to hidden content. It lets you break open locked chests—no key required—and is also a key component for crafting the powerful Power Hammer, which can destroy breakable walls throughout the manor and estate grounds.

What the Sledge Hammer Does

• Breaks open locked trunks and chests

• Saves your Keys for other locks

• Required to craft the Power Hammer in the Workshop

While it doesn’t open doors, it can crack open loot containers that would normally cost you a valuable Key.

Where to Find the Sledge Hammer

The Sledge Hammer is randomized, so it won’t appear every run—but here’s where to look:

• Commissary:

  • Costs coins, and inventory changes daily

  • Can sometimes include the Sledge Hammer for sale

• Workshop:

  • Occasionally found on tables inside

• Green Rooms:

  • Especially in the Greenhouse or Courtyard

• Dead-End Rooms:

  • Such as the Attic, Closet, or Walk-In Closet

• Toolshed (Outdoor Room):

  • Often contains tools like the Shovel or Sledge Hammer

  • Requires unlocking the Garage Door and West Gate to access

How to Keep It Longer

Because most items are lost at the end of each day, your Sledge Hammer will vanish unless you stash it:

• Use the Coat Check Room:

  • Store your hammer before the end of the day

  • If you draft Coat Check in a future run, you can retrieve it

Used in Crafting: Power Hammer

To break walls, not just trunks, you’ll need to build a Power Hammer at the Workshop.
Here’s what you need:

• Sledge Hammer

• Battery Pack (often found in the Workshop)

• Broken Lever (often in the Security Room or Spare Room)

Craft the Power Hammer, and you’ll be able to smash through cracked walls—some of which hide valves, alternate Antechamber levers, or entire shortcuts to the Underground.

Final Blurb

The Sledge Hammer is your best friend when you’re low on Keys and tired of locked loot. Whether you're cracking chests or prepping to smash down a wall later, picking one up early can completely change your run. Just don’t forget to stash it—or you’ll be back to coin-flipping at the Commissary again tomorrow.
