This is just copy and paste from various places, so its not my own work.

If you want to go into extreme detail, then have a look at this site

Also a good YouTube channel with lots of advice on knifes, what to look for, how to do stuff

The most important thing when buying knifes is to try before you buy. Try getting to a cook shop and handling the Knifes. Just because people recommend them, does not mean you will like them. Weight, handle shape, handle material, blade shape are all very important and totally personal preference.

General knife care
  • Use wooden or composite plastic cutting boards only. Glass, ceramic, marble and steel will cause the edge to roll or chip. Bad. Don’t do it.
  • Don’t drop your knives in the sink. Not only is it a hazard to the person washing dishes, but you can also blunt the tip or edge.
  • Don’t put your knives in the dishwasher. The heat may damage wooden handles and the edges may bang against other cutlery or plates.
  • Keep your knives clean and dry. Sanitize if necessary.
  • Do not store your knives loose in a drawer. Use a block, magnetic strip, slotted hanger or edge guards. The magnetic strip is not recommended if you have children or inquisitive pets.
  • Finally, your knife is not a can opener, a screwdriver, a pry bar, box cutter or hammer. There’s a special place in Hell reserved for people who abuse their knives this way.

Again if you really want to be a pro, refer back to this guide.

Common Kitchen Knives
Chefs Knife
A modern chef's knife (also known as a cook's knife) is a utility knife designed to perform well at many differing kitchen tasks, rather than excelling at any one in particular. It can be used for mincing, slicing, chopping vegetables, slicing meat, or even jointing large cuts of beef or ham. In order to improve the chef's knife's multi-purpose abilities, some owners employ differential sharpening along the length of the blade.
The fine tip, used for precision work such as mincing, might be ground with a very sharp, acute cutting bevel; the mid-section or belly of the blade receives a moderately sharp edge for general cutting, chopping and slicing, while the heavy heel or back of the cutting edge is given a strong, thick edge for heavy-duty tasks. A Typical Chefs Knife by Global
There are two types of blade shape, French and German. The far more common German design features a pronounced curve towards the tip of the blade which allows the knife to be rocked up and down, chopping the food with the belly and heel of the blade. The French design is more triangular, with much less curve at the tip and a longer straight section of blade; it is designed to be pulled towards the user, slicing the food instead. Chef's knives are most commonly available between 15 cm and 30 cm (6 and 12 inches), though 20 cm (8 inches) is the most common size. Most chefs recommend using the largest chef's knife that is comfortable in the cook's hands.

Utility Knife
A utility knife is a medium-size knife of conventional pattern intended for a myriad of cutting duties. Whilst being too short and thin for heavier cutting tasks many home cooks appreciate a multipurpose knife that covers a variety of tasks. Utility knives can either have a plain edge blade or a serrated blade, some of which are considered tomato knives. They are usually between about 10 cm and 18 cm (4 and 7 inches) in length.

Paring Knife
A paring knife is a small knife with a plain edge blade that is ideal for peeling and other small or intricate work (such as de-veining a shrimp or cutting small garnishes). It is designed to be an all-purpose knife, similar to a chef's knife, except smaller. Paring knives are usually between 6 cm and 10 cm (2½ and 4 inches), as anything larger than about 10 cm or 12 cm (4 or 5 inches) is typically considered a utility knife, though the distinction is somewhat vague.

Bread Knife
Bread knives are a type of serrated knife, Bread knives are usually between 15 cm and 25 cm (6 and 10 inches), with 20 cm (8 inches) being a common length. The serrations on the blade make it ideal for cutting bread (and other foods with hard/soft composition).

Offset Serrated Knife
Similar to a bread knife an offset serrated knife has a serrated blade and an offset handle that ensures the cook's knuckles will not touch the cutting surface when the blade has cut all of the way through the food. These knives are particularly popular in sandwich shops and some manufacturers refer to them as deli Knives.


Meat Knives
Carving Knife
A carving knife is a large knife (between 20 cm and 38 cm (8 and 15 inches)) that is used to slice thin cuts of meat, including poultry, roasts, hams, and other large cooked meats. A carving knife is much thinner than a chef's knife (particularly at the spine), enabling it to carve thinner, and more precise slices. They are generally shorter and wider than slicing knives.

Slicing Knife
A slicing knife serves a similar function to a carving knife, although it is generally longer and narrower. Slicers may have plain or serrated edges. Such knives often incorporate blunted or rounded tips, and feature Granton edge (scalloped blades) to improve meat separation. Slicers are designed to precisely cut smaller and thinner slices of meat, and are normally more flexible in order to accomplish this task. As such, many cooks find them better suited to slicing ham, roasts, fish, or barbecued beef and pork.

Cleaver
A meat cleaver is a large, rectangular knife that is used in cutting meat. The blade, approximately 15 cm (6 inches) long, is very heavy, with a thick spine, enabling the knife to chop through bone and joints with relative ease. Many cleavers have a hole in the end to allow them to be easily stored on a rack. Cleavers are an essential tool for any restaurant that prepares its own meat.
The so-called 'Chinese Cleaver' or Chinese chef's knife is actually a form of general-purpose cleaver, most varieties being much thinner in cross-section than the Western meat cleaver. Despite the increased popularity of Chinese cleavers in the West, most home meat preparation is still undertaken with a boning knife.

Boning Knife
A boning knife has a sharp point and narrow blade. It is used for removing the bones of poultry, meat, and fish. Generally 12 cm to 17 cm (5 to 6 ½ inches) in length, it features a very narrow blade. A stiff boning knife is good for boning beef and pork, but a very flexible boning knife is preferred for poultry and fish.

Fillet Knife
A fillet knife is like a very flexible boning knife that is used to fillet and prepare fish. They have a blade that is about 15 cm to 28 cm (6 to 11 inches) long, allowing them to move easily along the backbone and under the skin of fish.

Ham Slicer
A ham slicer is a special type of slicer, with a long blade and rounded tip that is offered by some manufacturers. They are specially tailored to cutting ham, as they are generally thinner and more flexible. Stellar Ham Slicer

Steak Knife
A steak knife is used at the table (as opposed to the kitchen) to cut through especially tough foods, such as meat. It is somewhat like a serrated utility knife, though its purpose is different. A steak knife is usually about 10 cm to 15 cm (4 to 6 inches) long and usually serrated, though some are not. Most are also decorative, since they are set on the table with the silverware!


Small Knives
Peeling Knife
Also known as a Tourne Knife or Bird's Beak Knife, a peeling knife often has a pointed tip that curves downward (towards the blade). They are often used for many of the same tasks as paring knives. They can be used to cut decorative garnishes (such as rosettes or fluted mushrooms), slice soft fruits, or peel skins or blemishes. They are also used to make a cut known as a tournée cut in vegetables such as carrots.

Trimming Knife
Usually about 5 cm to 8 cm (2 to 3 inches) long, a trimming knife has a small, curved blade that is shaped somewhat like a boning knife. Trimming knives are ideal for small tasks such as decorating and peeling.

Fluting Knife
Usually about 5 cm to 10 cm (2 to 4 inches) long, a fluting knife has a small blade that is very straight. Fluting knives are ideal for small tasks such as decorating and peeling.

Cheese Knives
Cheese knives are designed for soft,hard and parmesan cheeses:Soft cheese knives are specially designed for slicing soft cheese often having holes in the blade to prevent the cheese from sticking.Hard cheese knives are sharp, so they can cut exact slices, and often have a forked tip, allowing them to be used as a serving utensil as well.Parmesan cheese knives are specially designed for slicing very hard cheeses and have very short, thick blades that allow the user to put pressure into the cut.

Rockwell Scale
In general, the harder the steel, the keener the edge it will take. However, a hard steel makes it more difficult to get that edge in the first place. So manufacturers leave the steel a little soft, theoretically making sharpening at home easier.

Generally low 60s is considered the best for home use. Hard enough to keep an edge, but not so hard its impossible to sharpen.

Henckel Twin Cermax Rockwell 66°
I.O.Shen Rockwell 62°
Global Rockwell 56° - 58°

Edge Basics - its important to sharpen in line with what the knife originally came with, unless you want to totally regrind the edge.

Most kitchen knives are flat ground, meaning that the blade tapers directly from the spine to the edge. Hollow ground, convex ground and saber ground blades are rarely found in the kitchen. I mention them only to confuse you.

Edges come in a variety of flavors. The most common are the V-edge, double beveled edge, chisel ground edge and the convex edge.

V-edges and double beveled edges are variations on a theme. The edge found on your kitchen knives is most likely a V-edge, meaning, oddly enough, that the edge bevels form a V, two surfaces intersecting at a line of (ideally) zero width.

A double bevel takes this idea a little further by adding a second, more acute, angle behind the edge bevel. This secondary bevel is sometimes called a back bevel or relief angle. It’s purpose is to thin the metal behind the edge. The thinner the edge, the greater the cutting ability. However, an edge that is too thin is susceptible to damage. So you add a smaller, more obtuse primary bevel to the very edge to give it the strength to avoid damage from impaction, chipping or rolling.

Chisel ground edges are primarily found on Japanese knives, especially sushi knives. The edge is ground only on one side. The other is side is flat. Hence they come in right and left handed versions. Chisel ground edges can be extremely thin and sharp. If the edge bevel is ground at 25 degrees and the other side is 0 degrees, you have an included angle of 25 degrees – considerably more acute than the average Western knife.

Am I the only one, who detest blades with special coatings or depressions in?
These don't mean food doesn't stick, these make food glue to the blade.
I had a great knife, not cheap either, but the stupid anti stick coating, was actually like bloody glue, same with depressions.

I find they do make a difference, they make the problem worse, you get a vacuum between the item and the knife. I prefer plain shiny metal myself.

it deepens what you do, I like a 6" chefs/utility knife. that's 90% of use a small 3" utility knife. Chinese chopper.
then you might want/need bread, carving, filleting etc.
it really depends if you just chop veg/meat or actually bone out meat/fish, cut bread, have a lot of roasts etc

medium size chef is the most used for me.

Anyone know where decent to get water stones?
No mount, no dual grit and sales 800, 1200 and 6000 grit.

Extra wide ones would be a bonus.

You lucky so and so. That place is amazing.

Can you handle the knifes to see how they feel, weight and handle wise, as most look to be in displays, or do they get annoyed.

They're too far apart in grot levels to start with, and they shouldn't be taking off more material. However they may make more if a grey sludge as it's smaller particles. should never more than double the grit level.
And starting at 800 is only ok, if knifed are well maintained. If it's a poor edge more like 320 and repairing a properly damaged edge 120 or 220 depending how bad it is.

Very nice indeed.
One day, one day. I'll get a very nice set. But not while I'm back Ina. Random shared house as everything always gets broken.

A Dremel, no you shouldn't use a dremel, that would be a nightmare to try and get an even grind.
Either wet stones or the Lansky 3 set knife sharpening kit.
