Chunk of Bladestone is an Upgrade Material in Demon's Souls.

In-Game Description

Ore wet with dew. Enhances knives, curved swords, spears, and so on.
An ore used to make weapons that take skill to rend enemies. Weapons can be strengthened by Bladestones up to a maximum of level 5. Using bladestones to enhance a weapon can cause them to become brittle, so exercise caution.


Slightly more common drop from Black Skeletons from 4-1 and 4-2

General Information[]

Although chunks of bladestone are significantly rarer than Shards of Bladestone, they are also much more common than Pure Bladestone (and drop from the enemies that also drop pure bladestone), so they usually aren't a limiting factor for those seeking to create a +5 Sharp weapon.
