Best knife sharpeners

Ensure your blade stays sharp by investing in an easy-to-use handheld sharpener. We tested simple pull-through gadgets to bring you a review of five best buys.

Best… innovation
*Star buy*

AnySharpAnySharp knife sharpener

Best bits: Compact size and suction pad base
Price: £9.99
Comments: This diminutive gadget is a smart invention – the smallest sharpener we tried, it takes up barely any kitchen space, and the lever secures the suction base to the surface incredibly firmly – so much so, you could sharpen one-handed. It feels safe, intuitive to use and after three pulls our blunt knife was very sharp.

Best… for overall sharpening 

ProCookProCook twin wheel knife sharpener

Best bits: Excellent sharpening stone and safe-to-use handle
Price: £27
Comments: This sharpened our knife beautifully and was probably the best sharpening stone of all. The handle places your hand a safe distance away from the blade area, and the suggestion of adding water to lubricate the wheels worked a treat.

Best… beginner sharpener

Lakeland

Lakeland compact knife sharpener

Best bits: Inexpensive price point, small kitchen footprint and ease of use
Price: £11.49
Comments: A good choice for a beginner cook and people with small kitchens, this small sharpener has a good grip and a comfortable mechanism. It’s intuitive and features two settings.

Best… for the outdoor cook

EKA FiresharpEKA Firesharp knife sharpener

Best bits: Transportability and quickness of sharpening function
Price: £25
Comments: A good choice for a budding Bear Grylls, this tiny, portable pocket sharpener could be fitted to a keyring. However, without a handle or suction mechanism, this requires a steady, experienced hand to use it safely. 

Buy from Knives and Tools


Best… ergonomics

Robert WelchRobert Welch Signature hand-held knife sharpener

Best bits: Super comfortable handle and sturdy feel 
Price: £22
Comments: This safe-feeling sharpener has only one setting but sharpens well. The handle is comfy and easy to hold, and the thumb guard makes it feel extra safe.

Buyer’s advice

Why buy? 

Knives are one of the most commonly-used pieces of kitchen kit, but you won’t get very far with one if it’s blunt. A good sharpener can make a top chopper out of even the cheapest of blades.  A ‘dull’, unsharpened knife is actually less safe to use than a sharp one, and some professional chefs will even sharpen their knives daily.  


What should I buy? 

Lots of knife enthusiasts swear by a traditional steel for sharpening – but in actual fact this metal rod ‘hones’ a knife, which is essentially realigning the blade and not, strictly speaking, sharpening it. This knife skills video shows you how to use a steel. Whetstones usually come as a flat block of stone, and while they’re very efficient, require a certain amount of skill to use them properly. Hand-held sharpeners are usually small, compact and the best choice for home cooks or beginners – they often come with a safety guard and the wheel action is very intuitive to use. For that reason, we tested handheld sharpeners only. 

Knives


What we looked for

Ease of use and comfort: We looked for sharpeners that can be used by people of all skill levels. 
Sturdiness and steadiness: A sharpener that feels robust and is steady in the hand and on the work surface.
Safety: A top priority – waving sharp pieces of metal around is no trifling kitchen matter. We looked for sharpeners with safety functions and guards to protect against nasty accidents. 
Sharpness: The ultimate test. We looked for sharpeners that quickly and efficiently grind a knife to optimum sharpness – a freshly-honed knife should be able to cut through a piece of paper. 
Groundness of blade: We marked down sharpeners that left blades with rough edges.
