What are fishing knife sharpeners?

A fishing knife sharpener is a tool that you use to clean the knife or hone its edges so that it is capable of clean and efficient cutting. Over the years, knife sharpeners have evolved with the advanced ones even available as electrically powered.

Regardless of the type however, knife sharpeners generally consist of a hard surface – such as stone – that is used to run the blade along to remove nicks or ‘chunks’ and to make the edge smoother leading to increased sharpness.

What should you be looking for?

The following outlines some factors to consider as you look for a good sharpener for your fishing knife.

  1. Type
  2. Ease of use
  3. Sharpening material
  4. Grit number
  5. Safety feature
  6. Additions


Here are the different types of knife sharpeners that you can choose from:

  1. Sharpening stone: This is one of the oldest means of knife sharpening where the blade is run across a stone block. This knife sharpening method requires more time and effort than running your knives through an electric sharpener, but the tool gives you a good result.
  2. Sharpening steel: This has many names such as honing steel, butcher’s steel, chef’s steel. It could be ceramic or diamond-coated steel that helps restore the knife’s sharpness.
  3. Handheld sharpener: This type is typically small in size, lightweight, and easy to operate. Traveling fishers prefer such sharpeners since they can be easily tucked into their fishing backpacks.
  4. Electric sharpener: Electric sharpeners are ideal for people who prefer the least amount of effort approach in knife sharpening. There is no need to do anything manually; these sharpeners work automatically and can provide excellent results for restoring the sharpness of your blades.

The trade-off for the convenience of electric sharpeners would be their bulky construction and price tag.

Ease of use

Electric sharpeners have built-in motors that sharpen the knives quickly and efficiently. Manual products, on the other hand, come with an easy-to-read manual giving you the best practices on how to optimize their use. Other sharpeners are foldable that they can be placed inside the pockets of your fishing jacket.

Sharpening material

The materials used as abrasives by a sharpener can really separate the best knife sharpeners from the rest. Diamond is the hardest and most durable of all whilst polished ceramic, tungsten carbide and sapphire are less durable but less expensive.

Grit number

In sharpening stones, grit refers to the coarseness of the material which determines the type of result you want and the knife’s condition. To sharpen a knife with chipped edges, use a sharpener with less than 1000 grit. For a dull knife, the grit range would be from 1000 to 3000 will work best whereas 4000 to 8000 grit is good for the finishing process to refine the edge of a knife.

Safety feature

This is achieved by ensuring that the knife sharpener remains in place when you are using it to avoid accidental cuts. The standard safety feature here is placing non-slip pads beneath the product. Handheld products have ergonomic handles which give the user a firm grip on the sharpener.


Other potential additions include:

  • Slot system: Many knife sharpeners consist of slots that are used to achieve a thorough sharpening result.
  • Safety glove: Certain manufacturers include a safety glove when purchasing their products. This is helpful because the item is cut-resistant, protecting your holding hand as you sharpen the fishing knife.


Why do you need a sharp knife for filleting fish?

A sharp knife makes the process of filleting fish more efficient and precise. A dull knife requires more force to cut through the fish, which can be time-consuming and tiring – not to mention tends to leave half the flesh on the bone. A sharp knife, on the other hand, allows you to slice through the fish with ease and speed.

My three recommendations broken down
