# Iron Spike *Adventuring gear* - **Cost**: 1 sp - **Weight**: 0.5 lbs. Iron Spikes come in bundles of ten. As a [Utilize](3-Mechanics/CLI/rules/actions.md#Utilize) action, you can use a blunt object, such as a [Light Hammer](3-Mechanics/CLI/items/light-hammer-xphb.md), to hammer a spike into wood, earth, or a similar material. You can do so to jam a door shut or to then tie a [Rope](3-Mechanics/CLI/items/rope-xphb.md) or [Chain](3-Mechanics/CLI/items/chain-xphb.md) to the Spike. *Source: Player's Handbook (2024) p. 228.
