If you're looking for a spear shaft, there are a few things you can use. Here are some options:
-Wood: This is the most common type of spear shaft and is usually made from hardwoods such as oak or maple. You can find these at most hardware stores.
-Metal: Metal shafts are also an option, though they're not as common. They're typically made from steel or aluminum and can be found at some sporting goods stores.
-Composite: Composite shafts are made from materials like fiberglass or carbon fiber and offer a lighter weight alternative to wood or metal. These can be harder to find, but some sporting goods stores carry them.
Whichever material you choose, make sure the shaft is strong enough to support the weight of your spearhead and whatever else you plan on attaching to it.
