By using the knife properly and doing your sharpening regularly, you will have a knife that always delivers the best results regardless of the task in question.

This is important if we take into account that we often use different types of knives on camping, hiking or on numerous other enjoyable outdoor activities.

Pros of Having a Portable Knife Sharpener

It’s cheaper

In the long run, investing in a portable knife sharpener is less expensive than professional sharpening services.

Reduces risk of damage

When you sharpen your knives, you learn more about their blade condition, edges, and handle. You become more committed to its maintenance and preservation. Consequently, this lowers the chances of damage and prolongs your knives’ life spans.

You’ll always have sharp knives

Professional sharpening of your knives requires effort, time, and delayed food prep. On the other hand, having a sharpening tool in your kitchen or outdoors enables sharp knives anytime and anywhere and fast.

Cooking will be safer and easier

Working with dull knives doesn’t just increase the risk of injuries, but also prevents even cuts and can lead to spoilage. With a sharp knife, food prep and presentation is fast and simple.

Improves your cooking skills

In addition to prepping and serving tasty meals, a good chef should have sharpening skills- sharpening your own knives makes you the ‘king’ and ‘queen’ of your kitchen. Plus, working with sharp knives will make cooking more fulfilling.

What to Look for in a Pocket Knife Sharpener?

Before you start your search for the perfect pocket knife sharpener that will meet all your needs, preferences, and budget, remember to stay away from the cheaper options.

They may provide the needed results, but this is often a short-term thing. Plus, they can damage your knife, which is never a pleasant experience!

On the other hand, more quality sharpeners are usually a bit more expensive, but this is because they are made from durable materials and by reputable manufacturers. Hence, you will spend a bit more, but the sharpener will serve you long-term and optimally.

Below, check out what to look for in a pocket knife sharpener before you consider it for purchase.

  • Adjustable angles- when you have this type of sharpener, you can sharpen your blade at the same angle it was designed without having to change the edge geometry and the knife’s primary purpose.
  • Hard surface- when searching for the most suitable pocket knife sharpener, go with the one which has an abrasive hard surface. This surface is measured in grit- the higher it is, the finer the surface is.
  • Sharpening stages– a quality pocket knife sharpener should come with several sharpening stages, for example, one to restore the shape of the blade and another one to polish it.
  • Safety first- a quality sharpener for your pocket knives should offer safety features, for example, a barrier between the blade and fingers to prevent injuries
