To reach the Pure Nail in Hollow Knight, take the Old Nail to the Nailsmith in the west of the City of Tears and complete four refinements. The upgrades raise damage from 5 to 21 and cost 7,050 Geo plus six Pale Ore in total. You can upgrade in stages; you do not need all six ore before your first visit.
How the Nail upgrade path works
The Nailsmith reforges the Nail in a fixed order. The first refinement costs Geo only; every refinement after that requires both Geo and Pale Ore. Costs below are the in-game requirements listed by the community-maintained Nail reference; the smith’s location and role are described in the Nailsmith reference.
| Nail | Geo cost | Pale Ore | Damage |
|---|---|---|---|
| Old Nail | — | — | 5 |
| Sharpened Nail | 250 | 0 | 9 |
| Channelled Nail | 800 | 1 | 13 |
| Coiled Nail | 2,000 | 2 | 17 |
| Pure Nail | 4,000 | 3 | 21 |
The four upgrades together cost 7,050 Geo and consume six Pale Ore. The damage column gives each Nail’s listed damage, not the amount added by that refinement.
Where to find the Nailsmith
The Nailsmith’s workshop is in the western part of the City of Tears. Bring the Geo and ore required for the next refinement, then speak with him to have the Nail reforged. You can return for later upgrades as you collect more materials; an intermediate upgrade does not require having the ore for all remaining tiers.

Where to find all six Pale Ore pieces
The six Pale Ore pieces are awarded or found in different parts of Hallownest. Their locations and stated conditions are listed in the Pale Ore reference.
- Ancient Basin: Find the ore west of the tram station, near the main entrance. Two Lesser Mawleks guard it.
- Seer: Gather 300 Essence with the Dream Nail to receive the Seer’s reward.
- Hallownest’s Crown: At the top of Crystal Peak, find the ore embedded in the Radiance statue. Mantis Claw is required; Monarch Wings and Crystal Heart are recommended.
- Nosk’s lair: In Deepnest, break the wall in the room west of the Hot Spring, enter the lair, and defeat Nosk.
- Grubfather: Rescue 31 Grubs to receive the reward.
- Colosseum of Fools: Complete the Trial of the Conqueror.
Plan your upgrades around the ore you have
The requirements let you improve the Nail before collecting every Pale Ore. Start with the 250-Geo Sharpened Nail if you have not found ore yet. For the next tier, save 800 Geo and one ore; the Coiled Nail needs 2,000 Geo and two ore, while the final Pure Nail costs 4,000 Geo and three ore. You can choose among the listed ore sources based on your current abilities and progress. The source conditions establish what each reward requires, but do not establish a single fastest or easiest route.

What happens after the Pure Nail
After completing the Pure Nail, you can spare the Nailsmith. If you do, he later appears at Sheo’s hut in Greenpath after you acquire Great Slash and then rest or use a Stagway.
