ROCK TOOL: Obsidian Arrowheads (Pack of 10)
With this rock tool, students are always fascinated when something mundane like a rock is formed into something useful like an arrowhead.
These recently-made large arrowheads were hand-crafted from volcanic obsidian.
Each is unique. A great demonstration tool when teaching about Native Americans, igneous rocks, or man’s early use of tools.
Each arrowhead measures 50 -75 mm long.
Sold in pack of 10.
(*Caution: Arrowheads are sharp.)
