Pocket knives are incredibly handy tools that can be useful for a variety of situations while you’re traveling, whether you’re going camping or just going for a day trip, a small portable pocket knife will always have its uses.

Buyer’s Guide

While knife sharpeners can be very easy to use once you get the hang of them, before jumping straight in it is always worth researching some key considerations about a sharpening kit that can make it very effective and durable in the long term. 

This is extremely important for pocket knives as they require regular maintenance to stay at their best, and rather than buying multiple sharpeners one after another which can end up costing a large amount of money, it can be more worth your time just quickly checking some of these factors listed below.

Material & Grit Level 

The material of a sharpening stone or device is incredibly important because it can dictate how fast and how well a knife’s blade will be sharpened.

Ceramic is one of the most common surfaces and is made up of combined ceramic particles combined and turned into one stone.

Ceramic stone is one of the most efficient ways to sharpen blades and can come in a variety of grit levels to choose from.

Diamond coated stones and layers are often a little better than ceramic simply because it does not wear out being the hardest natural material on Earth.

Diamond coated sharpeners are known for removing material extremely quickly so you won’t need to sharpen long, the only downside is that when you first get a diamond sharpener it can sometimes remove material too quickly, however this is mitigated over time.

Grit level found on most sharpeners is also incredibly important with each level providing for particular kinds of knives:

  • 400 – 1000 grit: Perfect for fixing big gaps and restoring sharpness to damaged or chipped edges 
  • 1000 – 3000 grit: Quickly sharpen small edges of knives and can sharpen knives and tools that are only slightly dull 
  • 3000 – 8000 grit: Ultra fine finishing, makes the edge of most knives extremely sharp no matter how dull and refines the blade with a polished finish 

For pocket knives, up to 3000 grit will often be enough to efficiently sharpen a blade even if it is just a little dull, however don’t be afraid to test higher grit levels for more efficiency and durability in the long term.


Because pocket knives are made for portability the size of a sharpener should match this.

Knife sharpeners that are easy to use, compact but still made of good and sturdy materials are the best options to use for pocket knives since they have been known to dull fairly easily when using them outdoors, so a handy sharpener that you can bring out at any time is ideal.

Bigger sharpeners can still be used and are often more accurate and will leave a blade sharper for longer, they are however much heavier and harder to take into the field so it can be a better idea to use them at home to sharpen up any pocket or other knives ready for an occasion.


The angling required to sharpen a knife is one of the trickier parts of honing a blade and is where the most accidents happen, this is particularly the case with pocket knives which are often smaller and require that extra bit of precision. 

Always look for an angling guide or reference on a sharpening kit as these can save you having to memorize the exact positioning needed to sharpen certain knives.

Better yet, some sharpeners have adjustable angling toggles that can create the angle for you, largely mitigating any mistakes from happening.

It is often agreed that for most knives a 15 to 20 degree angle is perfect for providing the best results.

For a blade cutting through softer materials you can use an angle under 10 degrees while cutlery is often between 15 to 17.

Pocket knives which often experience more abuse are usually refined at a 17 degree angle and can reach up to 30 depending on the sturdiness and weight of the blade.

Any angles over 30 degrees are often reserved for larger edged blades that rely on staying sharp for their particular purpose, these include machetes, cleavers and axes.


Pocket knives are the best type of knife for the outdoors, they are sharp, portable and extremely handy when you may find yourself in a tricky situation.

This however means that the blades will become damaged rather quickly from the intensive cutting and chopping you could be doing, so a sharpening kit for pocket knives is especially important to make sure it doesn’t fail on you unexpectedly.

While smaller and more compact models are often the go to when it comes to pocket knife sharpeners, bigger and more accurate sharpeners are still very effective so feel free to browse the available options and consider some of these listed products that can all help keep your pocket knife sharp and reliable.
