The 'glass' you may be thinking of is obsidian -- actually a translucent stone that native peoples chipped and honed into sharp-edged tools.
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.
During the times when there were quite a bit of Native Americans still living in the US, people, including military leaders traded guns for some of the things that the tribes had. The Native Americans had not seen or used a gun before and this was much better than the weapons they were using, so they took on using guns as part of their everyday life. Which is also why there were so many Native American revolts against the "White men" otherwise known as the commmon citizen back then.

As the name implies, they're made of obsidian. A form of glass produced by volcanic action or exposure of sand to a very intense heat source. The arrowheads are flaked in the same manner as a flint arrowhead but tend to be much sharper and more brittle and prone to damage.
* Battledore - a flat wooden paddle used to shape molten glass objects * Blowpipe - a long, hollow, rod that shaped glass objects * Caliper - used to measure the size of a molten glass object * Crucible - a fire-resistant clay pot in which glassmaking objects were melted * Lehr - a special oven used to strengthen the glassware * Pincers - pliers used to stretch and squeeze glass * Pontil - a long metal rod connected to a molten glass object to help hold it * Pucellas - tongs used to twist and stretch a molten glass object * Shears - scissors for cutting and trimming a molten glass object
Most of scalpels are made of steel (hardened, tempered, stainless, high carbon). Some of them are also made of titanium, ceramic, diamond or obsidian (natural volcanic glass).
Obsidian is an extremely sharp type of glass, so it is often used to make knives and scalpels.

Glass can always be cut by diamond, so if precision is required over a variety of glass types, diamond will be preferred as the cutting tool.
Cutting in one direction in glass tubing will reduce the places the glass will crack and break. Cutting in multiple directions greatly increases the chance of the glass tubing completely shattering when you break it off.
Diamond is harder than glass, so a diamond will 'mark' glass. Glass-cutting takes place when the worker uses a diamond-tipped tool to mark the glass along the cut line, then applies pressure to the glass on both sides of the mark. Glass-cutting tools are tipped with industrial diamonds, which are 80% of all diamonds mined.
