Types Of Knife Sharpeners


Whatever type of knife you own, it will surely get dull over time if you actually use it. And once it gets dull, you should really consider sharpening it to bring your knife to good use.

When sharpening a knife, the outer layers of the steel or metal material gets removed to bring out a fresh layer that is sharper. You can sharpen your knife using several sharpening tools including a sharpening stone, ceramic stick, and an electric sharpener.

When sharpening a knife, the outer layers of the steel or metal material gets removed to bring out a fresh layer that is sharper. You can sharpen your knife using several sharpening tools including a sharpening stone, ceramic stick, and an electric sharpener.

The easiest and quickest type of knife sharpener to use is the electric sharpener. All you'll have to do is put your knife's blade against the sharpener and wait for it to be restored to its original shape.

Ceramic sticks and sharpening stones, or whetstones on the other hand, might take a little longer to sharpen a knife. Sharpening stones would also require a form of lubrication such as water for whetstones and oil for an oil stone.

Knife Sharpening Basics


You might think that sharpening a knife is easy, and that all you will have to do is rub your knife against the sharpener and you're done.

Well, knife sharpening can actually take some time before getting used to. There is a proper way to sharpen a knife, and if you fail to do so, you might end up damaging your knife beyond repair.

When sharpening a knife, you should always be under a bright light. You are after all handling a sharp object.

If it's your first time sharpening a knife, you may try marking the sharp edge of your knife with a marker. Doing so will help you see how much metal is being removed from your blade.

The next thing you should be mindful of is your blade's angle. When sharpening a knife, you blade must be at 20 degrees. If you are sharpening a pocket knife or a hunting knife, you might want to set your knife at 25 to 30 degrees depending on its size.

Once you find the right sharpening angle, you should sharpen one side of the blade with the rough grit, and rotate your knife back and forth while maintaining your angle until the new layer of metal is exposed.

How Often Should You Sharpen A Knife?


The number of times you will need to sharpen your knife would heavily depend on how frequent you use it. If you want to maintain your knife's sharpness, I suggest sharpening it as soon as you feel it getting dull.

Another technique I recommend is that you should try sharpening your knife with a few pulls using a sharpener before you actually use it to keep it from getting dull.
