Types of kitchen knives are not literally mean to its sharpness or dullness but it has divided into a lot of type in accordance to its use. Professionals nowadays want there cooking to be as fast as they can and in relation with that there must be an easiest way to cut those ingredients whether they wanted it to have some styles.
Here are some of the different types of kitchen knives:
Boning Knife:
Butter Knife:
A small knife with a blunt edge blade that is used to apply spreads, such as butter, peanut butter, and cream cheese, on bread or dinner rolls. Butter knives will generally be the same pattern as the flatware set they come with but there are also many individual butter knives available with patterns that range from very plain to very ornate.
Cheese Knife:
A kitchen utensil that is thinly shaped to cut easily through soft or hard textured cheese. Bladed cheese knives are typically manufactured with narrow-blades or short wide blades. Quite often, the narrow-bladed version will have a forked tip that is used as a lifter for pieces of cheese as they are cut. This knife may also be referred to as a forked-tip utility knife, which is used as a bar knife for cutting through citrus fruits or spearing garnishes, such as pickles, onions or maraschino cherries, for drinks as may be required.
Wider or heavier bladed knives are generally produced to accompany a cheese plate containing uncut cheese. Since cheese begins to harden as it is exposed to air, cheese is often kept whole when placed on plates or trays requiring the cheese to be cut as it is served. Shorter knives work well for this purpose, enabling the person cutting to slice through soft to firm textured cheeses.
Chef's Knife:
Also called a cook's knife, this knife is an all purpose kitchen knife that is used for most types of chopping, dicing, mincing, and slicing.
Chef's knives come in various lengths of 6, 8, 10, and 12 inches. The smaller sized knives are typically referred to as mini chef's knives while the longer lengths are known as traditional chef's knives. The heft, weight and balance of this knife allow it to be used for heavy duty work with thicker cuts of vegetables, fruits and meats. The length of the knife you purchase is significant. The longer the knife, the heavier and more difficult it will be to handle. Small handed cooks should choose shorter blades while large handed cooks will prefer longer blades.
Cleaver:
A knife with a wide rigid blade that is approximately 6 inches in length and tapers to a sharp cutting edge. This tool is used to chop, shred, pound, or crush food ingredients and materials. The blade of the cleaver is thick, somewhat heavy and well balanced with a beveled cutting edge. The beveled blade allows for ease of chopping through vegetables or hard materials, such as bones. The flat blunt side of the blade can be used to pulverize meat. If the handle is flat on the end it may be used to crush seeds, garlic or other similar ingredients. A hole is typically provided on the top end of the blade to allow for ease of hanging this tool when storing.
Filet Knife:
A knife consisting of a thin flexible blade, typically 6 to 11 inches long, used for filleting fish. The narrow blade enables the knife to cleanly move along the backbones of the fish, in and around areas adjacent to bones, and to evenly slice along the skin, removing it easily from the flesh.
Santoku Knife:
A type of knife commonly used to prepare ingredients for Asian food dishes. This knife is very similar to a chef's knife with a wide blade that has a long straight edge curving up slightly at the end. The main difference is that the santoku knife has a wider blade that is thinner in thickness, shorter in length, and curves up very gradually at the end providing a straighter cutting edge. Constructed of high-carbon stainless steel, stainless steel, ceramic, or titanium, this knife will typically be expensive to purchase, since it is precision made to be well balanced and well formed for ease of handling and greater control. With a thinner blade than a chef's knife, the santoku can cut smoothly and more precisely through dense vegetables, which may have a tendency to provide more resistance when using thicker width blades.
Versions of this knife are manufactured with either a standard-edged blade or a hollow ground edge, also known as a granton edge. The purpose of the granton style blade is to assist with keeping particles from sticking to the knife edge as it chops small bits of food as well as a friction reducer to provide less drag when chopping, which enables easier and faster motion. Santoku knives are used for chopping, dicing, and slicing foods into narrow or fine pieces so they can be added as ingredients to enhance the look or flavors of the various foods being prepared. This knife also works well for butterflying boneless chicken breasts, providing a manageability and ease of handling for the cutting required to butterfly poultry.
Serrated Knife:
A serrated knife with a long blade is used to slice through food that is hard on the outside and soft on the inside, such as slicing through the hard crusts of bread. A serrated knife with a short, thin blade is intended for slicing fruits and vegetables.
Carving Knife:
Generally made of a fairly thin blade that is at least 8 inches long and has little flexibility. The blade has a pointed tip designed to aid in cutting meat away from the bone. The carving knife works well to slice hot meats such as roast beef and roast pork. Often the carving knife comes with a carving fork that is used to anchor the meat while carving.
A knife used for cutting main courses such as steak and chicken. The knife usually has a blade that is 4 to 6 inches long and varies in thickness. Depending on the manufacturer, the blade may or may not be serrated. Since serrated knives cannot be sharpened, they require less sharpening maintenance than the straight-edged blade, but eventually the serrated edge becomes dull and requires replacement. To lengthen the life of the serrated blade, do not wash the in the dishwasher. The dishwasher detergent will dull the blade.
