A glass knife is a knife with a blade made of glass, with a fracture line forming an extremely sharp cutting edge. Glass knives were used in antiquity due to their natural sharpness and the ease with which they could be manufactured.
Knife blades can be manufactured from a variety of materials, each of which has advantages and disadvantages. Carbon steel, an alloy of iron and carbon, can be very sharp. It holds its edge well, and remains easy to sharpen, but is vulnerable to rust and stains.

Blade
The blade is the central part of the knife and what you will be using to cut most of the time. Most blades are made of metal with a sharp edge. The kind of metal used will depend on the type of knife you want. It is the quality of the blade that determines the quality of the knife. Here are the different parts of the blade:
Bolster
The bolster is only found on forged knives. It is where the blade and the handle meet and can be essential to help keep your fingers from slipping up onto the blade. It will usually have a “lip” on one side that helps protect skin when you are cutting food. Bolsters can be of different lengths; some may extend down to about half the length of where the blade and the handle meet, while others may only be about an inch long strip of metal that is welded to the blade and extends past the handle....
Tang
The tang is the extension of the metal that runs from where the blade connects to the handle and down into a point. Tangs can also be full, partial, or rat-tailed. Full tang runs the entire length and width of the handle and is the most preferred for better coverage and a sign that the knife is of better quality. The partial tang runs half or just part of the length of the handle. Rattail tang is found in Asian knives, which means a tapered tang. Sword making also uses this method.
Plunge Line
The plunge line on the edge of a knife is the point where the blade meets with the handle. The plunge line may have different shapes depending on which part of the world that it comes from. A Western-style is called a toe or a spitzer grind. It has a beveled edge and looks like an elongated triangle. It has two symmetrical side curves that meet at the tip, making it easy to create smooth and accurate slices. Eastern-style plunges can take many forms: concave, convex, dish ground, and double b...
Choil
The choil is the unsharpened portion of the blade at the very back end. It’s where your fingers go to help you control chopping motions, and it can also be used as a makeshift thumb rest when cutting with a rocking motion.
Ricasso
Ricasso is the part where the blade becomes thick before the handle.
