Hollow Knight Silksong Grindle Location & NPC Guide
Grindle is one of the more curious NPCs in Hollow Knight Silksong. Found locked up in The Marrow, he introduces himself as a thief, but freeing him gives Hornet new rewards and a vendor who sells secrets for Rosaries. This guide shows where to find Grindle, what happens when you release him, and why it is worth doing.
Where to find Grindle
Grindle is imprisoned in The Marrow. After defeating the Bell Beast, continue heading east until you reach a prison building. Inside, climb to the cells and you will see Grindle behind bars.
Breaking open the cell frees him, starting his role as an NPC vendor.
Rewards for freeing Grindle
Freeing Grindle unlocks two key rewards. First is the Straight Pin, a red Tool that acts as a projectile. Jump into the upper cell above his prison to find it. This makes Hornet much safer against ranged enemies.
Second is Grindle’s information service. After resting at a bench and returning, he will relocate near a bench in The Marrow. From there, you can spend Rosaries to buy secrets about hidden areas, bosses, and progression.
Grindle’s vendor services
At first, Grindle charges 10 Rosaries for his tips. Each purchase increases the price of the next. While he does not sell items, his secrets often reveal shortcuts or important discoveries.
These purchases are optional, but they are useful if you want to find hidden upgrades without endless searching.
Should you free Grindle
Yes. Freeing Grindle has no downsides in the early game. You gain a strong early Tool in the Straight Pin and unlock a vendor who sells information.
There are no known negative consequences for freeing him, making it an easy choice.
Final Blurb
Grindle in Hollow Knight Silksong may call himself a thief, but for Hornet he is a reliable ally. Rescue him in The Marrow, claim the Straight Pin, and check back later to buy his secrets. His help makes exploration smoother and combat safer, making him one of the more valuable NPCs in Pharloom.
