How to Sharpen a Pocket Knife

Sharpening a pocket knife is neither difficult nor tedious. In fact, all it requires are four steps, which are:

Recognize Your Angle

To sharpen your knife, you need to be sure of the angle the blade of your knife was initially finished to. If you don’t know this, check it out in your user manual.

Before Sharpening, Clean Your Knife Thoroughly

Make a solution of gentle dish detergent and warm water. Then, using a toothbrush, scrub the knife edge with a nylon pad and WD-40.

Eliminate Debris

With the help of a good lubricant, remove any metal debris or swarf which develops when you grind the blade and hone it. The lubricant also cools the blade which heats up, avoiding any chances of the blade warping.

Select Your Knife Sharpener Carefully

Since certain knives match well with particular sharpeners, thereby giving better sharpening results, you must choose your sharpener wisely.
