There are the all important knives we use for preparing and cooking nutritious meals, the dining sets we use to sit down and eat with families each day, and the functional knives that help us enjoy the wilderness and our favorite pastimes such as hunting and fishing.

With so much use, it's no wonder that these miracle tools can often become blunt quite quickly, and therefore become fairly useless as a tool.

Why Having A Quality Knife Sharpener Counts

When you think about how often we rely on our knives, from the kitchen to the outdoors, it's a wonder that more households don't have a quality sharpener in their homes already. However, this useful accessory isn't as common as it should be, mainly because people don't understand just how far reaching the benefits can be.

  • More precise cut - The absolute most important benefit to having a knife sharpener means you will always have the sharpest knives on hand. This means a more precise cut and less work from you, whether you're cutting a steak or filleting a fish on the lake.
  • Saves money - Rather than throwing away your old utensil set or hunting knife every time you think the blade has worn down, a simple sharpening can get them even sharper than the day you bought them. Knives can last for over 20 years with a professional sharpening system at home which will save you thousands over your lifetime with this one device.
  • Adds safety - When you're working with a blunt knife you're more at risk of slipping out or jarring the knife which can cause injury. Having both work tools and kitchen knives sharp and precise can ensure you are working as safely as possible in whatever job you might be doing.
  • Faster work and preparation - If you've ever tried doing anything with a blunt knife you know it can take twice as long, so you should always have a sharp knife available. Spending a little time each month keeping your knives sharp will reduce hours from meal preparation time so you can get on with other tasks at home.

All of these benefits can be available to you when you invest in the best knife sharpener for your needs. If you're willing to spend so much on quality knives and kitchen utensils, it makes sense to put the same amount of effort into choosing a knife sharpener that can offer you so many benefits on top.

Features To Consider With Your Knife Sharpener

Choosing a knife sharpener doesn't need to be a complicated process, provided you have in mind a bit about its use beforehand. There are a few main features to consider when shopping for a knife sharpener, as there will be more than just one style and purpose out there to suit everyone and every blade you have at home.

Abrasive Type

This is the material that will be doing the hard work, so you want to choose a sharpener that offers something tough. A popular choice is 100% diamond thanks to its toughness, however, there are other options such as oil stone.


The angle of a knife sharpener refers to the angle between the blade and the stone. The smaller the angle, the sharper the knife will be. The most common angle for a chef's knife is usually 15 degrees, and some electric ones don't give options to adjust this amount.

Those with adjustable angles can go up to 35 degrees for things such as cardboard cutters or knives used for thick rope.

Type Of Sharpener

There are three main types of knife sharpener, divided into how they are operated. First, an electric knife sharpener does all of the work for you as you pull it through.

Second, a pull through knife sharpener is a manual device which requires you to pull it through and sharpen it yourself. Finally, a sharpening stone which allows you to sharpen the knife by pulling it over the stone.

Blade Suitability

Some knife sharpeners are only made to suit one style of knife, but more and more these days you will find a knife sharpener that can work with both plain edge and serrated knives, offering far more versatility.


The warranty feature on a knife sharpener is especially important on an electric device as there is more chance of fault, so look for a minimum of 12 months which includes all mechanical and electrical failures.

The best way to know exactly what features are right for you is to look at the blades you have at home and surroundings to determine what might suit them.

For the home chef who wants their kitchen filled with the sharpest and most precise blades, you're going to be looking for something completely different to the outdoor adventurer who relies on knives for their hunting and fishing outings.
