[F967]Furi Knife Sharpening System

by Bianca Bartegi, Bia

Knife sharpening has come a long way from the traditional bench stone. Although these are still available, a wide variety of other tools are now available to sharpen every type of knife or cutting device. The knife sharpener you choose will depend on the tools you need to sharpen and your personal preference.

Grinding wheels have abrasive grains throughout that cut away chips in the material and sharpening the knife. A variety of abrasive substances are used in wheels. Aluminium oxide is the most common material found in wheels. Varieties of different types of oxide are used and are designated by a letter and a number. Aluminium oxide is great for sharpening steel, bronze, wrought iron and annealed iron.

Zirconia alumina is a blend of aluminium and zirconium oxide. This combination makes for a very durable wheel. It is good for sharpening a wide range of steels and alloys. This material is the next most common substance used after aluminium oxide.

Ceramic aluminium oxide is one of the newest materials used in grinding wheels. It is a very strong material and is used when precision is needed. Ceramic aluminium oxide is often blended with another abrasive material. The substance it is blended with varies according to the purpose and material it is being used to sharpen.

Wheels come in a variety of shapes. A straight wheel is the most common. These have a front facing cutting edge. A cylinder wheel is another common shape. These wheels have the cutting edge on the front of the cylinder.

The grit size is another consideration in choosing the right wheel for the job. A lower number, for example ten or twenty four, is a coarse grain wheel. A larger number, like 100 or 180 is a fine grain. Fine grains are good for finishing work as they remove smaller pieces of metal from the edge of the knife.

A Bench Grinder for Knife Sharpening

Bench grinders are inexpensive tools that are used by many to sharpen knives. They can be used to sharpen a variety of objects, including knives, cutters, hand tools and drill bits. They can be mounted on your workbench. The wheels come in six or ten inch diameter sizes. The motor used in these varies from 1/3 to 1 horsepower. A good bench grinder has a tool rest to keep the wheel steady and improve accuracy in sharpening.

Chain Saw Sharpeners

If you own a chainsaw, you will need a chain saw sharpener. Automatic sharpeners are the easiest method available to sharpen a chainsaw. The chain is locked in place when the wheel is lowered. Position the tooth and set the angle on the sharpener. Pull the head up when finished and position the next tooth. Automatic sharpeners ensure uniform sharpening.

Manual sharpeners are less expensive. They are also precise and work with all types of chain. A manual lever is used to lock the chain in place. Manual chain saw sharpeners often come with more than one wheel. This makes them more versatile and ensures they will work with your chain.

Ceramic knives are made out of zirconium oxide. They aren't metallic whatsoever and have a flat, off-white to bright white color. Their composition is much harder than steel. Actually, they're second only to diamonds, which are the hardest mineral of all. Isn't that something?

There is another class of ceramic knives that have black blades. These blades start out as white zirconium oxide. With an additional firing process called sintering, they are converted into black zirconium carbide. This process gives the blades the advantage of being even tougher than before. Now they are the strongest knives out there.

There are definite advantages of ceramic knives over steel knives.

◦ Edge Longevity. Because ceramic knives are harder than steel knives, they can hold a sharp edge much longer. Generally, most ceramic knives can hold their edge for months if used correctly.

◦ Easy Use. Because they hold their edges longer, ceramic knives are easier to use than steel knives. There's less sharpening to be done. Not only that, they are so much lighter than steel knives.

◦ Wear Resistance. Ceramic knives do not stain or rust. They will not become discolored by food acides.

◦ Chemically non-reactive. You needn't worry over whether or not your food will taste or smell like metal. Isn't that great?

◦ Simple To Clean. Ceramic knives are non-stick. It isn't ever necessary to use special cleaners or abrasives to get them clean.

Just as there are advantages, there are a few pretty important disadvantages to using ceramic knives.

◦ Expensive. Ceramic knives are usually more costly than steel knives. This is because zirconium oxide is a fairly advanced material and costs more than steel. In addition, imported ceramic knives, as most of them are, have a high import tax that adds to their price tag.

◦ Edge Fragility. Quality ceramic knives are not likely to shatter when dropped. They are, however, likely to gain a chipped edge or a broken tip. Even though ceramic knives are very strong, their edges are quite fragile. Cutting bone or anything of similar hardness, then, is out of the question.

◦ Breakable Blades. If you use your ceramic knife as a prying tool, you've got a very good chance of snapping the blade at the handle. Just don't do it. While your knife isn't meant for prying, the fact that the blade could actually snap in two when strong pressure is applied leaves room for concern. Use it only for cutting.

All in all, you are advised not to sharpen ceramic knives. When customers purchase ceramic knives, they are urged to let the manufacturers be the ones to sharpen them up. If that isn't possible, they're advised to bring their ceramic knives to a machine shop.

Sharpening a ceramic knife is not the same as sharpening a steel knife. It is a whole new animal. You've really got to already be a skilled sharpener. However, with good skill and the right tools, you really could sharpen them yourself.

Ceramic knives are truly amazing. They are highly efficient. Usability may be limited, but where you can use it, watch out. They are quite extraordinary.
