The sharpening stones and safety rods fit inside the plastic base for easier portability, which serves as a convenient carrying case with a lid.

Buying Guide: What to Look For in a Pocket Knife Sharpener

Compact Size

If you want the ultimate option in portability to accompany your little pocket knife, look for a knife sharpener that is built to fit in your pockets as well. Some of these compact knife sharpeners will be designed with folding rods or extendable sharpening surfaces so that the overall footprint of the device is smaller when folded away.

You can also find retractable sharpeners, such as the Wamery Pocket Knife Sharpener discussed in detail above.

Note that these smaller sharpeners may be less effective at sharpening large blades.

On the other hand, if you want a more stable option, you will have to go with a less pocket-friendly tool. For example, the Work Sharp Knife and Tool Sharpener will produce the most consistent results, as it is electrically powered and sharpens via moving flexible abrasion belts. However, this device clearly will not fit into your pockets and is best used on a workbench.

For easier portability, look for a knife sharpener that weighs less. While some of the heftier devices may weigh over a pound, you can find more lightweight options, even down to less than an ounce.

However, similarly to our discussion on size above, keep in mind that more lightweight sharpeners will be less stable on their own and require more hand stabilization. Also, be sure as well that you are not skimping on quality just for the sake of having lightweight materials.

When searching for a new pocket knife sharpener, look for products with an abrasive surface built to last while sharpening your blades successfully over time. These surfaces should be diamond, tungsten carbide, ceramic, or aluminum oxide. These types of surfaces will produce the most consistent sharpening output over repeated uses.

A diamond sharpening surface is very quick to sharpen and holds its shape well, as diamond is a very hard surface. Tungsten carbide is another extremely hard surface that is good for coarse sharpening of very dull knives. Ceramic surfaces are often finer grit, making them effective at polishing to create an ultra-sharp, smooth edge.

When considering quality, also think about safety. The most high-quality, safest sharpeners will likely include integrated finger guards to keep your fingers away from the sharp edges.

Most of the pocket knife sharpeners we’ve reviewed in this product round-up are multifunction, meaning that they can successfully sharpen more than one type of blade and angle. This is important because it makes your sharpener more versatile.

A versatile sharpener will include sharpening surfaces with more than one grit level, such as coarse, fine, and medium. It would be best if you also looked for a sharpener that features a built-in angle guide to ensure that you are sharpening your blade at the proper angle so as not to ruin the knife. Most pocket knives will be sharpened at 10 to 15 degrees.

If your sharpener features a leather strop, this means it can keep your blade at the ultimate sharpest edge. This is, after all, one of the major reasons why the Work Sharp Guided Field Sharpener was our pick for number one in this product round-up.
