The knife was one of the first tools used by early humans, and in the past thousands of years its use and its design have evolved considerably. Today there are several different kinds of knives, made from a variety of materials, and used as tools, for cooking and other purposes. Let’s take a look at the main types of knives that are presently available.

Carbon Steel

Carbon Steel has been used in the making of blades for many years. Knives made from carbon steel are tough and take a better edge with little effort. However, carbon steel blades discolor when they come in contact with foods that are high in acid, such as tomatoes and citrus fruit and the blades must be treated with care to avoid discoloration and rusting. If you are using carbon steel knives you should wash and dry them thoroughly after use. Some box cutter and utility knife blades are made from carbon steel.

Stainless Steel

Unlike carbon steel, stainless steel blades do not discolor or rust, however, they are not hard enough to maintain the best edge. Some utility knives and box cutter blades are made from stainless steel.

High Carbon Stainless Steel

Knives made from high carbon stainless steel offer a combination of the best attributes of carbon steel and stainless steel blades. They have the toughness and ability to hold an edge and, like stainless steel blades, they do not discolor when coming in contact with acidic foods.

Titanium

Titanium blades are made from a mold of titanium and carbides. When compared to steel, titanium is lighter, more wear resistant, and holds its edge longer. The titanium blade is more flexible than steel, they work best for tasks such as boning and filleting.

Ceramic

Ceramic blades are made of zirconium oxide and aluminum oxide. Although they are much more delicate than steel knives, they tend to hold their edge up to 10 times longer. However, once the blades have dulled, they must be sharpened by a professional.

Plastic

Plastic knife blades are primarily used in order to prevent vegetables and other edible items from becoming discolored from the blade of a knife. Plastic blades are not very sharp and require some force when cutting.

Hollow Ground

Hollow ground knife blades are manufactured with a process that fuses two separate pieces of metal together. After the pieces are fused, a beveled blade edge is created. Although these blades often have very sharp edges, the blade lacks the balance and longevity of a taper ground blade. This type of blade is most often found on knives that are used less frequently.

Taper Ground

Taper ground knives are manufactured with a single sheet of metal and are ground so that they taper smoothly from the spine to the cutting edge. This type of blade can be found on knives that are used frequently.

There you have it. These are the most common types of knives that are commonly available. The next time you buy a knife think about how you will use the knife and then choose one constructed from the materials that best match your purpose.

If you’re a person who has many knives, many edges to sharpen at a fairly consistent pace, electric knife sharpening is for you. So much time and effort will be saved. But take heed. Using these devices without proper training and only a little experience could be a regrettable move.

Electric knife sharpeners are well known for producing great heat while sharpening. Friction from the metal edge against the sharpener over time will do that. You’ve got to know just how hot you’ll allow the metal edge to get. If your blade changes color on you, if you’re waiting for that to be the sign, you’ve blown it. If you see sparks, forget about it. Your blade edge has been overheated and has lost its temper. Yeah, you’ve got an angry knife on your hands! (Ha!) No. To lose temper on a blade means that you have weakened it. Made it brittle, even pliable. Just imagine using it now. That is a knife that you don’t want.

Even knowing that, electric knife sharpeners have improved a great deal over the last decade. Some of them are astonishing in what they claim they’re able to do. Many are quoted as saying that they “will never detemper” a knife’s edge. Wow. Wouldn’t that be something? To never, ever have to worry. Truly amazing.

What about the sharpening angle? This is the angle of the bevel that determines the functionality and durability of each knife. Some modern electric knife sharpeners have high precision knife guides that it is said will achieve the exact sharpening angle they want, precisely. You needn’t concern yourself over it. Some sharpeners actually claim that they will do as much as convert the existing sharpening angle of some knives to a different, more high performing sharpening angle. Another says that it’ll get the edge to a condition that is better than the factory edge. It’ll give it a sharpening angle that performs better than that given by the one’s who’ve made the knife. Truly awesome declarations, one and all.

Many of the latest electric knife sharpeners have improved to having several sharpening stages all in one. The first stage is meant to get the edge to sharpness. You could stop right there if you wanted. The second stage is usually a finer sharpening with smaller abrasive particles than is found in the first stage. It is meant to get the edge to razor-sharpness. The third stage is meant for stropping. How about that? An electric knife stopper to get your edge silky smooth. Absolutely extraordinarye.

Electric knife sharpening has truly come a very long way. If everything they claim is true, why would anyone want to know how to manually sharpen their knives? A very good question. Here’s your answer: It isn’t possible to take most kinds of electric knife sharpeners away from home and out into the field. Many of them are battery powered but they’re size or bulk doesn’t make transport very practical. It isn’t very wise to take an electric knife sharpener out camping or on a fishing trip. You really shouldn’t take it out on a boat or on a hunt. With electric knife sharpeners, you’ve got to be near an outlet or in a secure and safe location.

Many times then, it just isn’t sensible. Too many times you’ll need to sharpen your knife’s edge right where you are, where all you’ve got is yourself, maybe a pack and your own two hands. But most of all, more than all of this, sharpening on a sharpening stone will still get you the sharpest edge possible. It is still the most reliable way to sharpen your knives.

If you only need to sharpen your knives while you’re at home, an electric knife sharpener is probably all you’ll ever need. But if you’re an active individual who often needs to do some sharpening while you’re out in the world, you’ll want to learn how to sharpen knives with your own two hands. And don’t worry. You’ve got many choices to make that happen.

Knife sharpening isn’t difficult. It just takes a bit of practice. Once you’ve got it, you’ll have a very valuable skill that’ll last your lifetime. You can do it anywhere, anytime. Isn’t that something all by itself? And when you’re home, surrounded by the many advantages of modern living, your electric knife sharpener can get your knife sharpening done for you in two flashes. Truly incredible, to be able to manually and electrically sharpen your knives. There’d be no circumstance you couldn’t overcome.

The first knives were most likely made of wood, bone and other perishable materials. These ancient tools were shaped by knapping, or percussive flaking of rock, such as obsidian and flint.

As advances in metallurgy were made, materials such as wood, stone, and bone blades were gradually succeeded by copper, bronze, iron, and eventually steel. During the Middle Ages, knives joined the fork and spoon as the prominent pieces of cutlery in the western world. As a result, much of the world’s population was exposed to knives as a daily utensil and tool.

Today’s knives come in many shapes and sizes but can be categorized between two types: fixed blade knives and folding, or pocket, knives. Blades may be serrated or plain, or even a combination of both. Some knives contain a tang, a portion of blade that extends into the handle.

Fixed Blade Knives

Unlike its earlier predecessors, blades of today can be manufactured from a variety of materials, each with its advantages and disadvantages. An alloy of carbon and iron, carbon steel is very sharp and is easy to sharpen, but is susceptible to rust and stains. An alloy of iron, chromium, nickel, and molybdenum, stainless steel is not able to take on quite as sharp an edge as carbon steel, but it is highly resistant to corrosion. Intended to combine the best attributes of carbon steel and stainless steel, high carbon stainless steel blades are able to maintain a sharp edge and do not discolor or stain.

Laminate blades are created by a layer of harder, more brittle steel that is sandwiched between an outer layer of softer, tougher stainless steel to reduce chances of corrosion. Pattern-welding is another technique similar to laminate construction, which welds various steel types in layers, but then the stock is manipulated to create patterns in the steel. A lighter, more wear resistant metal, titanium is more flexible than steel, although it is unable to take as sharp an edge. However, carbides in the titanium alloy allow them to be heat-treated to a sufficient hardness. Largely immune to corrosion, ceramic blades are very hard and lightweight blades, able to maintain a sharp edge for years at a time with little or no maintenance. Ceramic blades may only be sharpened on silicon carbide sandpaper and some grinding wheels.

Forging & Stock Removal

Steel blades are commonly shaped by forging or stock removal. Blades are forged by heating a single piece of steel and shaping the metal while it is hot with a hammer or press. Stock removal blades are shaped by grinding the removing metal. After shaping with both methods, the blade must be heat treated, which involves heating the steel above its critical point and then quenching the blade to harden it. Once the blade is hardened, it is tempered to remove stresses and toughen the blade. Forging tends to be used for more high-end product cutlery lines.

Folding Knives

Connected to the handle through a pivot, the folding knife’s blade is able to fold into the handle. Folding knives are typically created with a locking mechanism to prevent the blade from accidentally closing on the user’s hand.

Found most commonly on traditional pocket knives, a slip joint holds the open blade in place by a spring device that allows the blade to fold if a certain amount of pressure is applied. A lockback includes a pivoted latch connected to a spring, and can be disengaged only by pressing the latch down to release the blade. Other types of popular locking features include: liner lock, frame lock, button lock, and axis lock.

Life of the Knife

Throughout history, knives have served various purposes – from cutlery to weaponry. Here are a few of its uses:

Knives as Weapons

Bayonet Knife – a knife-shaped fighting weapon attached to the muzzle of a rifle or similar weapon.

Combat Knife – any knife mainly intended for fighting

Trench Knife – Purpose-made or improvised knife intended for close-quarter fighting, particularly in trench warfare.

Shiv – prevalent in prisons, this knife is a crudely homemade weapon out of everyday materials

Switchblade – A knife with a folding blade that springs out of the grip when a button or lever on the grip is pressed

Knives as Tools

Electrician’s Knife – An insulated knife used to cut electrical wire

Diver’s Knife – A standard part of diving dress, the diver’s knife has been adapted for use in diving and water sports

Hunting Knife – Used to dress large game

Pocket Knife – Also known as a multi-tool, the pocket knife contains several blades, as well as other tools

Utility Knife – Used for cutting sheet materials, including moving boxes, cardboard boxes and shipping and receiving containers.

Your cooking experience will not be the same if you do not have the best kitchen knife around. The knife is one of the most important tools in the kitchen, not only for the professional cook or chef, also for the beginner and the avid cook a good and quality knife will make sure that the work is done well.

Meat and poultry will not be cooked to perfection when they are not cut the right way. This is the same with vegetables. They have to be sliced properly so they will look succulent and enticing to eat.

Ever seen recipes and prepared meals from magazines or on television? What makes them extraordinary is the way the food is arranged. Try having a taste of some of them. Chances are, they will not taste as good as they seem to be.

Your basic kitchen knife is basically the secret how your food will be presented to those who will be eating them. With the use of your kitchen knife, you can really cook everything to perfection and make everyone’s mouth water just by looking at them.

How do you look for the best kitchen knife?

1. Look at the shape and style.

Different knife styles are used by different people for different purposes. For example, the cook’s knife is primarily used for heavy-duty cutting. They are heavier and longer than most ordinary knife. Dicing, chopping and slicing can be done using the cook’s knife.

Slicing knife is smaller than and not as long as the cook’s knife. It is used basically for slicing soft or large cut of meats.

While bread knife has smaller blades. They are not as sharp as the other kinds of knives because they only cut soft portions of types of breads. A bread knife will become dull when it is used for cutting food stuff other than bread.

2. The knife handle.

The handle of your knife can be made from different kinds of materials. Some of the more basic ones are stainless steel, composite, plastic and wood.

Plastic knife handles can be made into any shape you want it to be. They can also be designed so that it will snugly fit your grip. The modern makers of these types of knives are making use of computer enhancements to determine the best shape and mold.

The process of making a great set of knives is not as simple as it seems. There is a certain level of artistry and science that goes into knife making. If you want to learn about how the blade, grind, and handle come together to make some of the cleanest and most beautiful designs of sharp and ready-to-use knives than read on.

There are different types of finishing that can be used to make the knife have its unique look. If you have a knife that was finished in the stonewash fashion than it will have that sort of vintage or antique look right away because of the abrasive pattern on the knife. IF you get a knife with a vibe finish than it will have some abrasions, like the stonewash finish, but not quite as many.

Knives are heat treated to turn them into their sharp final products. Annealing is one step that helps knives out and treats them with high heat before they cool. Hardening allows knives to use a combination of annealing. Tempering is a process that controls how the cooling process is done on the knives.

If your knife has 13% chromium or more than most knife experts would tell you that your knife is “stainless steel.” This isn’t exactly accurate because with misuse your knife could still rust. Even though this is the case, it will still take a long time for this to happen. You can also choose from non-stainless steel blades that can be even better and last longer than those that claim to be stainless steel. You may wonder why you’d want a blade that won’t give you as much protection against rust, but there are reasons to consider it. Damascus steel is a combination of metals and this greats a great looking knife!
