Pocket Knife Sharpener FAQs

Best Pocket Knife Sharpeners

If you are using a pocket knife regularly, there are a few things you must know before making your purchase, to get the best results and most convenience out of your sharpener.

How often do I need to sharpen my pocket knife?

How often you need to sharpen your pocket knife depends on how often you use it, as well as the materials that you are cutting. If you use it once a month or less and you’re cutting paper, lightweight plastic or other types of softer materials, you will likely only need to sharpen it 2 or 3 times a year. On the other hand, if you use it very often and you’re cutting a wide variety of materials or harder materials, your pocket knife should be sharpened approximately once a week for the best cutting results.

Backpackers and campers should sharpen their camping knives before each trip. It’s important to have a sharp, efficient blade when it counts.

Does the angle on the pocket knife blade make a difference?

Yes, it does. If you sharpen it at an angle that’s more narrow (approximately 12 degrees) it will be better for jobs like slicing and filleting. With an angle of 20-degrees or more you’ll have a blade on your pocket knife that’s best for rough chopping. Note that some sharpeners come with an angle guide if this is important to you.

How many times should I pull the pocket knife through a sharpener to get the best results?

Surprisingly, all it takes is about 5 to 10 strokes to make even the dullest of pocket knife blades sharp and ready to go once again. More than that and you’ll possibly get a slightly better edge but not one that will be noticeable.

What is the difference between honing and polishing a pocket knife blade?

Honing is what you want to do if you want to return your pocket knife’s blade to its optimal ‘V’ shape. One caveat is that, if your blade’s bevel and edge are very badly worn, coarse sharpening needs to be performed first. Polishing creates an extremely sharp and very small micro-bevel (razor-sharp in fact) so that’s what you should do if you need a very sharp edge fast.



Final Thoughts

A sharp knife is an effective one! Whether you are using your knife on camping trips, in your garden, or just throughout the day, a pocket knife sharpener can make a world of difference. And it fits right inside your pocket! 

Additionally, many of these sharpeners can be used on all types of blades. You can use them to sharpen backpacking hatchets, backpacking saws, and even large kitchen cutlery knives. They’re a great tool at an affordable price point. Stay sharp!
