SAVE 50% On Our Long-Term Preparedness Guide + Worksheets

One of the oldest and most essential survival tools is the knife. In the wilderness, knives are used for a wide range of tasks, from creating feather sticks to batoning to skinning an animal. It takes many years for knife users to learn what survival knife they like the most, why they like it, and how they can make the best use of it in every task.

Along with this, users also need to learn how to maintain their blade and have a sharp blade at all times – a dull knife will do no one any good when they are out in the wilderness and facing life and death situations.

When buying a survival knife sharpener, you need to put in as much thought into it as you do when buying a knife. Here is a look at some of the things to keep in mind when buying a decent knife sharpener:

  • Remarkable Performance: One of the most important features to look for in a sharpener is its ability to produce a consistently smooth edge that does not have any scratches or nicks in it. Always pick a sharpener that performs well when you use it on your knives.
  • An Abrasive and Hard Surface: Generally speaking, the hardest sharpening material is diamond – it is also the fastest. After diamond, tungsten carbide and polished ceramic come next. You measure abrasiveness in terms of grit, which means that the abrasive is finer when the grit number is higher.
  • An Accurate Angle Guide that You can Adjust: There are some sharpeners that make it easy for even users without experience to hold the blade at the correct angle while a little bit of practice is required in others. The best angle guides can be adjusted to accommodate more than one blade angle, especially 15 and 20 degrees.
  • Adequate Safety Features: A sharpener should come with safety features that allow you to avoid cutting your finger while you are sharpening your blade. There are a number of sharpeners that do not come with enough safety features or the right safety features – avoid them no matter how good looking or cheap they are.
  • Multiple Sharpening Stages: With a coarse abrasive, you can reshape the edges on knives that are extremely dull or damaged. Finer abrasives are mainly used for polishing and touch-ups. It is essential to have both because you will remove too much steel from your knife if you use a coarse material to polish or touch up your knife.
