carbon steel blade, but it is very resistant to staining and discoloration. Some people think the discoloration imparts a flavor into the food.
High Carbon Stainless Steel blades combine the best of both worlds. They do not discolor like the carbon blades, but they can be sharpened to a keen edge that is long lasting. They do not impart any flavor into your food.
Titanium alloy blades are lighter and more flexible than steel blades. The carbon in the alloy allows them to be heat treated so they will hold an edge well. They do not impart any flavor into your food, either.
Ceramic blades are made from ceramic. They are extremely hard and will hold their edge for a long time. They will cut the glaze on a dinner plate and should only be used on a cutting board. The down side is that they must be professionally sharpened.
Plastic blades are not very sharp and are specialized in the use in the kitchen. They are used to cut vegetables so they don’t turn dark.
Laminate blades are made by layering different materials together. The number of possibilities is endless. The only way to decide if you want one of these types is to buy and try.
Steel blades are either forged or stamped.
Forged blades are made in a detailed process that takes a lot of time and is accomplished by skilled craftsman. I will not go into detail here, but this type of blade is more often than not preferred by chefs.
Stamped blades are designed to be made in mass. The quality of the metal used is such that it can be worked quickly into a finished product. This type of knife is less expensive than the forged one, but it must be replaced on a regular basis.
The Business Edge
The type and design of the knife edge determines how it should be used.
Flat ground blades are tapered from the backbone to the edge. This blade is very strong but is heavy.
Hollow ground blades look a lot like the flat ground except starting about halfway up the blade it is ground into a concave shape. It is weaker than the flat ground blade but has the advantage of being lighter.
The Serrated blade looks like a saw. It is ideal for cutting things that are hard on the outside and soft on the inside. It actually tears the food rather than cutting, so it should not be used for all kinds of food.
