The simplest documented route to Frankfurt steel is the Cave in Apollonia, in Trosky: find the key inside a cracked skull in the chest room, then open the locked chest for two pieces. Other caches are reported across Trosky and Kuttenberg, while a Trosky Castle blacksmith is a possible purchase option after story progression.
What Frankfurt steel is
Frankfurt steel is a blacksmithing material in Kingdom Come: Deliverance II. Gamer Guides’ item database lists its in-game weight as 1.0 and price as 20.0; those values describe the item entry, not a real-world measurement or guaranteed sale price. The database description identifies it as steel used as raw material for weapons and armour. The sources do not establish a recipe unique to Frankfurt steel or a special performance bonus.

Get two Frankfurt steel in the Cave in Apollonia
This is the clearest documented route. PC Gamer’s guide, updated 15 July 2026, places the Cave in Apollonia in eastern Trosky and describes the following path:

Pick the symptom - the matching free tool is one click away.
- From Trosky Castle, take the road north. Follow it as it loops east through the trees and then turns south into Apollonia; the cave is on the right.
- Enter the cave and follow the passage, climbing the two ladders to reach a room with a locked chest in the middle.
- At the far end of the room, look on a ledge for a sack with a cracked skull resting on it. Search the skull to find the chest key.
- Use the key on the chest. It contains two Frankfurt steel, 200 Groschen, and other valuables.
Other reported map locations

Merchant and Semine alternatives
ScalaCube reports that a blacksmith at Trosky Castle can sell Frankfurt steel after the story has progressed through Wedding Crashers and For Whom The Bell Tolls. Treat this as a possible option rather than guaranteed stock: merchant availability may depend on progression.
The same guide reports three pieces in a chest in the horse trader’s barn at Semine. It says the key is on a wooden pillar near the horse pasture. This location is less strongly corroborated than the Apollonia route.

Which route should you choose?
- For a straightforward, documented find: use the Apollonia cave route for two pieces and a key hidden in the same room as the chest.
- For a larger reported cache: the Trosky cliffside sack contains three pieces, but reaching it may involve a drop from above.
- If you are already exploring Kuttenberg: its two reported caches involve either a medium-locked chest in a ruined house or an underground room reached via an enemy camp.
- If you prefer buying: check the Trosky Castle blacksmith after the reported story milestones, bearing in mind that stock is not guaranteed.
