Best Knife Sharpener Reviews

Knife sharpeners are not the tools that people easily remember to pack when going on an outdoor-type of trip, or even a tool that most people remember to pick up at their local hardware shop for that matter. But this is definitely a mistake that needs to be rectified. For one, sharpening your knives, scissors and other tools should be on your mind quite often if you would like to keep them sharp and functional. Sharpening kitchen knives in particular is important and prolongs their usage and life, allowing you to spend your money on other things in life!

Sharpening tools are also a vital addition to every workshop. They will help you keep your other tools precise and functional. This will in turn allow them to last longer, and also minimize work related injuries. You might think nothing of it, but even gardening tools need to be sharpened every so often, and believe us, working with razor sharp tools will get the job done both faster and better.

The Best Knife Sharpeners​

Types of knife sharpeners

There are several types of knife sharpeners, from your ordinary ceramic sharpening stone and Japanese sharpening stone, to those more professional types, such as electric knife sharpeners and serrated knife sharpeners. Here we will take a look at the most common types of knife sharpeners, and the best and the brightest of the products in the bunch!

Pocket knife sharpeners

Gerber Bear Grylls Field Sharpener

Pocket knife sharpeners are the smallest and the most compact type of knife sharpeners. They are rather rudimentary but serve their purpose well. Their main goal is to provide you with a quick and easy way to sharpen your blades while out in the wild. You would be surprised how often that comes in handy, and how many times a sharp knife can say your life in dangerous outdoor situations.

Pocket sharpeners are sometimes not equipped to handle large or serrated blades but that is not the case with all of them. However, we do recommend packing sharp knives when going on an outdoor trip or a hunting party and using these only as backup. By all means, have them packed up whenever you are heading out as they are practically weightless and very affordable.

Diamond knife sharpeners

Premium 17-Inch Diamond Knife Sharpener Steel Oval Shaft

Diamond sharpeners are excellent for giving very dull blades a new breath of life. Diamond is a very strong and durable material that can sheer off even the strongest steel.

They are most often coated rods, not v-shaped indentations, as that makes them extremely versatile and allows them to be used on serrated blades. There require some time and expertise too, as you will need to know the correct angles in which different types of knives are sharpened! They are safe to use in ceramic knives.
