There are few things less useful than a dull knife.
A knife with no edge isn’t going to cut, slice, or pierce anything—making it nothing more than a cool-looking hunk of steel that serves zero practical purpose.
For your knives to serve any real use, they’ve got to be sharp. To make that happen, keep a pocket knife sharpener in your pocket, tool pouch, everyday backpack, or kitchen gadget drawer at all times. Whenever your knives get a bit dull, whip it out and with a few pulls of the blade, you’ll be back in business with a keener-than-ever edge.
Below, I’ve collected a few of the best portable knife sharpeners around, simple but ultra-practical tools to help you keep your knives hella sharp all day every day.
For a quick, efficient, on-the-job sharpening, this is the tool for you.

The sharpener is small enough you can carry it around anywhere you go, and it’s sized for everything from short-bladed pocket knifes to full sized kitchen knives. For the price, you won’t find many better and more versatile options.
