Finding the right knife sharpener for your needs

If you've ever ruined a perfectly good fruit or vegetable by cutting into it with a dull knife, you'll know the importance of keeping a knife sharpener handy in the kitchen! A sharp knife will allow you to cut cleanly through a piece of raw or cooked food without tearing it, whether you need thick medallions of beef or ultra-thin slices of fish. It's also much safer to cut food with a sharp knife as blunt blades can slip and make it easier to cut yourself.

No matter what your skill level, we have a knife sharpener to suit your needs. From fast and easy electric knife sharpeners to whetstones that give you control and precision, find the best knife sharpeners by leading brands at the lowest prices online at Kitchen Warehouse!

Importance of sharp knives when cooking

A sharp knife is key to cutting your food ingredients neatly into the size and shape you need for cooking. They are also essential for carving the food to perfection once it's cooked for serving. Razor-sharp blades glide effortlessly through meat, fish, vegetables, fresh herbs and more without crushing the food cells or damaging their appearance. It's less effort on the hand and wrist plus there is less chance of injury as a sharp blade is more predictable and sinks into food without slipping.

From sharpening stones to electric - various types of knife sharpeners to choose from

There are 4 different types of knife sharpeners available at Kitchen Warehouse. Each one has its own benefits and requires a different level of skill to use. They include:

  • Whetstones - A whetstone gives you ultimate control over how sharp you get your knives. It requires you to run the blade back and forth across the stone to sharpen it. The Edge Master Professional Combination Whetstone has a coarse grit side for sharpening and a medium grit side for refining with a non-slip base to prevent accidents.

  • Electric knife sharpener - This is a great one for beginners. Electric sharpeners have one or more slots to fit the blade into with sharpening stones that grind and sharpen the blade as it passes through.

  • Sharpening steels - This is also called honing steel. Rather than sharpen a knife, this product realigns the edge of the blade if it has been bent out of shape due to regular use.

  • Pull-through sharpener - A handheld sharpener is a manual knife sharpener that requires you to pull the blade through the slots to sharpen it. It provides the right sharpening angle but with more control than an electric sharpener. A water knife sharpener is a type of manual sharpener that can be used under water to prevent overheating the blades. The Yaxell 2 Stage Water Sharpener is a top choice.

Process of sharpening and honing explained

The process of sharpening stainless steel knives involves running the blade against a rough surface, usually a stone, until the edge is sharp again. The sharpening angle is important as it will determine the sharpness and durability of the knife edge. A 20 degree angle works best for most knives.

Stones have different grits to both sharpen and refine blades. A two step knife sharpener, such as the Edge Master Two-Stage Knife Sharpener, will have a coarse grit setting that removes steel from the blade and a finer grit setting to polish the blade. The Scanpan 3 Stage Knife Sharpener features three different in-built plates made from Tungsten, Diamond and Ceramic for sharpening, refining and polishing.

Honing a knife is different to sharpening it. With repeated use, a knife blade can get bent out of shape and require re-aligning. A sharpening steel can give your knife a straight edge again. In doing so, the blade is made more efficient and cuts as though it has been sharpened. To hone a knife, you run the blade down the steel at the same angle it's been sharpened at, making sure to hold that same angle during the entire process. Press slightly harder than the weight of the knife and swipe 3-4 times per side.

Features to consider when buying a knife sharpener

These features will help you to choose the right knife sharpener for you:

  • Grit - Knife sharpening grits range from under 1000 to restore chips in blades to 3000 grits for sharpening dull edges and 6000 grits for refinement.

  • Size - From the Victorinox Sharpening Steel 25cm to the compact Furi OziTech Foldaway Knife Sharpener, find a solution that fits comfortably into your kitchen space.

  • Time - An electric knife sharpener can get the job done in no time while a whetstone requires more time and patience to achieve stunning results.

  • Price - There are budget-friendly knife sharpeners to suit casual cooks and more expensive options that are excellent for professional chefs.

Electric knife sharpener vs. handheld - what's the difference?

An electric knife sharpener automatically spins the sharpening stones inside so that all you need to do is insert the blade into the slots and let the wheels do their work. The Chef's Choice EdgeSelect 120 Electric Knife Sharpener offers precision angle control with 3 settings for sharpening and polishing everything from a chef's knife to serrated knives and Japanese knives.

A manual or handheld knife sharpener requires you to move the blade back and forth yourself at the correct angle to sharpen and refine. They provide superior control but require more time, effort and skill to achieve best results. The Wusthof 2 Stage Knife Sharpener has Carbide wheels for restoring dull knives and ceramic wheels for honing and fine-tuning.

Storage tips to keep your knives sharp

One of the best storage solutions for retaining the integrity of your knives is a knife block. This useful kitchen tool keeps your knife set together and safely out of the way while ensuring the blades stay sharp and ready for when you need them.
