How to Select and Use a Knife Sharpener

Why did we bring this up out of nowhere? Well, some of you may have mastered the blade, but have you learned how to prolong its use by sharpening it? 

There are several reasons why some anglers, chefs, and the simple folk can't maintain the sharpness of their knives:

  • They are using the wrong knife sharpener;
  • They don't know what the right way of sharpening a knife is; or
  • They have the budget to buy a new knife, so they don't have a problem throwing away the blunt old knife.

We hope you don't fall under the last category. But we can help you with the first two points!

Below are the two types of knife sharpening tools and how to use them:

  • Whetstone is a rectangular block of sharpening stone that is available in three different abrasion levels. It works like sandpaper, where you push the knife to-and-fro across the stone's surface. While doing this, you must maintain a 30–40 degree angle to avoid damaging the blade.
  • Honing rod or honing steel is made up of fine ceramic or rigid steel. Even beginners can use it with minimal to no training at all. All you need to do is to rest the tip of the rod on your counter and slightly turn it at a 20-degree angle. Next, grab the knife and pull it across the rod, then towards you. Repeat this motion on each side of the blade with the same number of pulls.

Seek professional help. If the manufacturer of your knife provides sharpening services, then you should take advantage of it. But do take note that you will most likely be responsible for its shipping.

In closing

Choosing a knife for fish is a balance between functionality and budget. You may have bought an expensive and branded knife, but does it serve the purpose based on where and how you will use it? When buying a knife, it’s always best to look at quality first before price. Always check if its features and specs meet your preference; be practical. After all, a high-quality and reliable fishing knife is one of the essential tools you can depend on throughout your fishing career. Read more about this on our website.
