Old Fort, also known as the Fort San Cristóbal in Puerto Rico, was built using a common type of volcanic rock called "tuff." Tuff is a type of rock formed from consolidated volcanic ash ejected from vents during a volcanic eruption. It is a durable and easily workable material, making it suitable for construction purposes.
An extrusive volcanic rock which is erupted under water called pumice.
Solidified volcanic ash is called tephra or volcanic rock.
Pumice is a type of rock that is formed from volcanic foam. It is light in weight due to the presence of trapped air bubbles and is commonly used in horticulture and as a skin exfoliant.
Pumice is a light, porous volcanic rock that is commonly used in beauty and skincare products for exfoliation. It forms when volcanic lava rapidly cools and traps gases, creating its characteristic porous texture.

If you're asking what volcanic rock can be sharpened as a cutting tool, the answer is obsidian.
pyroxenite is an igneous rock, so there arent many uses for it. they can be used to build houses and/or sculptures, and since they are very hard, they can be used for weapons. again, the uses are not many.
There is no use for molten rock from volcanic eruptions.
Used to build houses
