The best kitchen knives are only as good as how well they are sharpened. No matter how much you spend on a knife there will come a time when it is no longer cutting at it’s best, making it not only harder to use, but also more dangerous as you are forced to put more force into each cut.

A good knife sharpener can bring your knives back to the time when they would glide through an onion before your tears had enough time to even start to well up. So read on and find out which steels, whetstones and sharpening gadgets made it onto our list of the best of the best.

What type of sharpener is for you?

The first thing you need to decide is what kind of sharpener do you want to use. The most traditional type is the sharpening steel, a textured metal rod with a handle at the end like a knife. Steels are used by running the edge of the knife along the steel and is the method you will often see portrayed in kitchens with the chefs wildly flailing their arms about – we strongly recommend you do not do this, believe us, we have the scars to prove it is not a good idea.

Steels are a good way of sharpening knives but it is work intensive and it can often be difficult to tell you are doing it properly.

Whetstones require a bit more time and work, but instead of holding the knife and steel in either hand you have the stone in front of you (after soaking it in water) and you rub the edge along the course side of the stone at an angle of around 20 degrees, followed by the smooth side of the stone. We find that this is a slightly easier way of definitely getting a good edge on a blade – and possibility the best way of getting the sharpest edge – but it does take a bit longer than using steel.

The other way of sharpening your knives is using either an electric or manual dedicated knife sharpener. These tend to have grooves you insert the knife into so you don’t have to worry about the angles or if you are doing it right. These are the fool-proof method of getting your knives in working order, and in the case of electric knife sharpeners are a quick and easy way of getting them back to their best.

Wusthoff Extra Fine Diamond Sharpening Steel – The best sharpening steel

Wusthoff Sharpening SteelIf you want a professional grade sharpening steel, this Wusthof is a fantastic option. The wide steel and extra fine finish allow you to get a consistent edge with greater polish, making it easy to restore a dull blade to full sharpness.

It feels exceptionally solid in the hand and is well balanced to give you extra control when you are using it. If we had one quibble, it is that the finger guard isn’t very large, so you will have to be very careful when using it, but you should always take care when sharpening knives regardless.

It’s not cheap at around £35-50, but it is very fine quality.
