i believe it was the sharp decline in the bison(buffalo) population.
still used by tribes today, the red-bellied piranha's teeth were used for hunting(spears), cutting food and hair, and also as tools to aid in building huts
They made powerful, sharp spears and cross-bows that are designed to hunt animals like bears, bisons, and moose. After the rifle and gunpowder was found, the native americans started using guns instead of spears for hunting animals.
Arrowheads (from Native Americans) are made out of a rock called flint. It is a tough, slick rock and when shaped and cut, can be fatally sharp.
Native Americans used a variety of materials for making knife blades, depending on the resources available to them in their specific region and time period. Some of the materials commonly used by Native Americans for making knife blades include: Stone: One of the earliest materials used for making knife blades by Native Americans was stone. They would shape stones such as flint, obsidian, chert, and quartz into sharp edges by knapping or flaking techniques. These stone blades were used for cutting, slicing, and butchering. Bone: Native Americans also used animal bones, such as deer antlers, to make knife blades. They would shape the bones into sharp points or edges by carving, grinding, or polishing. Bone blades were commonly used for cutting, scraping, and carving tasks. Antler: In addition to bones, Native Americans utilized antlers from deer, elk, and other animals to make knife blades. Antler blades were often shaped into sharp points or edges and were used for cutting, slicing, and hunting. Shell: Some Native American cultures used shells, such as abalone or clam shells, to make knife blades. They would shape the shells into sharp edges by grinding or polishing techniques. Shell blades were used for cutting, scraping, and carving tasks. Copper: In certain regions where copper was available, Native Americans used copper to make knife blades. They would hammer and shape the copper into sharp edges, which were then attached to handles made from wood or bone. Copper blades were used for cutting, slicing, and ceremonial purposes. Obsidian: Obsidian, a naturally occurring volcanic glass, was highly prized by Native Americans for making sharp and durable knife blades. Obsidian blades were formed by carefully flaking and shaping the glass into sharp edges. They were used for cutting, slicing, and ceremonial purposes. Overall, Native Americans were resourceful and skilled at utilizing natural materials to create effective knife blades for various tasks and purposes. The specific materials used for knife blades varied depending on geographic location, cultural traditions, and availability of resources.
Their hooves are very sharp--sharp enough to rip a human, horse or any other animal to shreds. The antlers of a bull moose are enough to gore or toss a human or animal as large as a big dog flying. Rutting bull moose and cow moose with young calves are far more dangerous than what you can ever give them credit to be.
BoneAnother AnswerThe 'glass' you may be thinking of is obsidian -- actually a translucent stone that native peoples chipped and honed into sharp-edged tools.
The red-bellied piranha's teeth are so sharp that tribes used them for their tip of their hunting spears, cutting hair, slicing food, as well as tools for building huts. The teeth from these piranha's are still currently used as devices to this very day!
