5 Best Kitchen Knife Sharpeners

Everyone who enjoys cooking knows that a chef's best friend is a sharp knife. Without it, things just don't get done as quickly or as efficiently. But how do chef's keep their knives in razor sharp condition?

With a sophisticated knife sharpener, which can often cost as much as the knife itself.

Crazy right? But today we're going to be looking at consumer grade knife sharpeners, you know those ones that won't break the bank.

If you're looking for a commercial knife sharpener, the type Jamie Oliver or Gordon Ramsey would be proud of you'll need to go to your local kitchen supply store.

A knife sharpener is the ultimate problem solver and most people don't realise they need one until they actually buy one.

You can slog away cutting fresh fruit and vegetables with a blunt knife, completely unaware that your life could be so much easier. Then you buy a knife sharpener and it all becomes clear.

Like a rice cooker in the kitchen, once you've got one, you can never go back to the alternatives you managed with before.

Why buy a kitchen knife sharpener?

Knives will always become dull and blunt through continual use. It's a fact of matter. Even washing them, especially in a dishwasher, will cause them damage.

Very often we will simply stop using them and replace them with expensive replacements, or cheap new ones which will also become blunt pretty quickly.

With a knife sharpener, you don’t need to produce unnecessary waste by throwing away those old dull knives.

You can just as easily give them new life by sharpening and restoring them with an easy to use and fairly inexpensive sharpener. Save money as well by not buying expensive new knives when you really don’t need to.

A good knife can last years, just ask any professional chef!

How do I keep my kitchen knives sharp?

Sharpening knives is a process which requires an implement or tool. Knife sharpeners come in a few different types.

There is the more traditional steel honing rod type which tends to be preferred by the professional kitchens and chefs. These are literally steel rods which you draw the knife blade down and across to sharpen it.

Then there are whetstone varieties which are also of the more traditional type. These are simply blocks of stone (natural or man-made) with a grit structure to ‘hone’ the blade, usually combined with oil or water.

And finally, there are the modern sharpeners which are hand-held implements with built-in sharpening slots which take no real skill to use. These are very popular with the general public as they are very easy to use and work perfectly well.

The process is different with each of the three types of sharpener so you will need to learn that once you have purchased one.

But whichever type you choose, keeping knives sharp is just a matter of doing it on a regular basis. It is not a complicated or a long process once you get the hang of it. And once you do, you will realise just how good it is to always have sharp blades in your kitchen!

Do knife sharpeners ruin knives?

Knife sharpeners of the more traditional varieties (honing rods and whetstones) have been around for centuries without any debate about whether they ruin knives.

Professional chefs and those who profess to be, how does one say this, ‘up with the Joneses’, will happily sharpen their knives with one of these methods.

But these same people have all sorts of issues with the modern easy-to-use knife sharpening implements which are quick, easy and require no skill to use.

The so-called ‘pull-through’ sharpeners. The argument they raise is that these sharpeners are way too rough and coarse with the blade and will wear away the metal of the blade.

There is no proof that this will actually happen. And the logic doesn’t really stand up to scrutiny either. A knife is made of steel, a very durable metal.

An occasional abrasion of that metal against another metal to create a new and sharper edge surely cannot do any significant damage or wear it down to any noticeable degree.

The indisputable fact is that these pull-through sharpeners work! That the other two types are more difficult to perfect as a technique.

If it were not for these new sharpeners many of us would probably still be throwing away our old dull knives and spending money on new ones.

How often should you sharpen knives?

The debate is open about how often one should sharpen kitchen knives. It very much depends on how serious a cook you are, the quality of your knives, the type of sharpening method you favour, and the type of use your knives get.

Jamie Oliver explains when to sharpen a knife.

For most of us, knives certainly need to be sharpened when they are becoming dull or blunt.

When they are not slicing through food like butter then it is probably time to think about sharpening your knives. If you favour the pull-through sharpener then you will be needing to sharpen your knives pretty frequently.

For those who favour expensive utensils and treasure them, the honing and sharpening process is almost a fine art.

The recommendation by those in the know is that these blades be honed quickly every time they are used to keep them up to par between being properly sharpened.

If they are properly looked after sharpening may only be necessary every year or two, again depending on use, quality etc.
