Best kitchen utility knives

We tested top-selling kitchen utility knives from Global, Lakeland, ProCook, Robert Welch and more to see which were sharpest and easiest to use for slicing, dicing and filleting
Joey Willoughby-Rainsford

A kitchen utility knife is best for cutting food that's too small or fiddly using a chef’s knife. The narrow blade and small tip should mean the best utility knives handle delicate tasks, such as thinly slicing fruit, and trimming and filleting with ease. 

In February 2022, we tested kitchen utility knives from Global, Lakeland, ProCook, Robert Welch and more costing from less than £10 up to just under £100.

We found that you don't need to spend big to get the best kitchen utility knife for sharpness, dicing, slicing, mincing and ease of use.

We originally tested 10 utility knives, but one has since been discontinued.

Pricing and availability last checked: 10 May 2022.

What's the best way to sharpen kitchen knives?

Knife being sharpened on whetstone

Even the sharpest blades will dull over time. Therefore, having a sharpener on hand can help you get the best out of your knife time and again. 

When we tested the best knife sharpeners, we found a whetstone combined with a honing steel gives the best results, but also requires a bit of a knack to do it properly.

If you don't know what you're doing with a whetstone, you could risk damaging the cutting edge of your knife. 

For most people, the easiest and safest way to sharpen your kitchen knives is with a handheld sharpener.

Where should your fingers be when using a kitchen utility knife?

To maintain optimum control and keep your fingers safe, you should hold the knife in your dominant hand with your index finger and your thumb near the front of the handle and press tightly against the flat sides of the blade. 

There will be an indentation or curved space designed for your finger and thumb to sit comfortably and safely on good knives.

If you need a bit of extra power in your slicing, you can place your fingers on the spine of the blade to help push down.

Your other hand should be kept in a claw grip while you're steadying the food on the chopping board (ie fingertips tucked under). 

How we tested kitchen utility knives

To single out the best kitchen utility knives, we put our selection through the following series of tests:

How sharp when new? 

We tested each knife to see how sharp they were when brand new. 

We did this by shining a light directly across the cutting edge of the blade. Reflections on the cutting edge are proof of dullness.

The fewer areas of reflection, the higher the knife was rated for sharpness.

How sharp for cutting? 

We then used each knife to cut through the following:

  • Paper We dragged each knife down through the paper in a slicing motion. Only the sharpest of knives are able to do this.
  • Chicken breast Diced.
  • Butternut squash Cut longways with our weight on the blade's handle, then cut into chunks.
  • Tomato Sliced through the centre horizontally on a chopping board. A knife needs to be razor sharp in order to do this in a single gliding motion.

The best utility knives were able to slice through everything with ease, but the worst got stuck or, in some cases, couldn't even breach the item.

Ease of use and comfort

Each knife was also rated on completing three basic kitchen skills. At the same time, we considered how comfortable each knife's handle was. 

While some knives felt comfortable to hold, the real proof of how comfortable they were was when using them.

We diced onions, minced garlic cloves and julienned carrots. 

The best knives were the easiest to control when completing these tasks, and also offered us secure and comfortable grips. 

On the other hand, the worst knives made these tasks more tricky and in some cases left us with sore hands.

How sharp after use? 

After all the other tests had been completed, we examined the knives' cutting edges again and compared the results with those we got at the start. 

The best knives maintained their cutting edge, while the worst dulled quickly.

Build quality

We checked each knife for any manufacturing flaws or faults while considering the design and shape of the blade and the handle, what the knives were made from, as well as how much care and attention had been put into the finishing touches.

The best utility knives impressed us with their well-considered designs and quality of craftsmanship, while the worst had issues with their handles and blades or had a couple of manufacturing faults.

How we chose these kitchen utility knives

When finding knives to include in our test we considered kitchen utility knives sold by at least one leading UK retailer.

We purchased all the products we tested and no food was wasted to bring you these results.
