Knife sharpening 101
There are two basics to getting the perfect edge – sharpening and honing. We’ll get to homing in a moment. For now, let’s discuss sharpening. Most sharping, or whet stones are designed to be used either completely wet, which is done by soaking the stone in water until completely saturated, or by using an oil designed specifically for sharpening. There are other ways, but most of us have seen the stone-type of sharpener. You draw the knife evenly across at the desired angle, often 20-degrees, but that varies. The key is, you have to draw the entire blade at the same angle.
Sharpening is drawing away microscopic amounts of metal, as well as smoothing any burrs. The actual edge of the blade will be sharp, but not smooth. For that, you will want to hone the blade.
And on to honing the blade
The smoothest part of the sharpening system, and the final step, is to hone it using a honing surface. That is often a ceramic surface, or extreme fine grit surfaces. If you’ve ever seen someone using a steel rod on a knife before cutting, this is a hone. It is polishing the edge for smoother cuts, and to knock down any small burrs. Honing is, and can be done much more often than sharpening. You can use a honing oil, too, to make the edge even more polished.
What is the best knife sharpener for beginners?
If you’ve never used any real sharpener before, look for one, like the electric models above, that has all the angles and directions taken care of for you. This makes it harder to ruin the edge and it gives you a great, sharp blade.
How often do I need to sharpen my knife?
The obvious answer is – when it goes dull, but it’s not that drastic. Often a knife that feels dull just needs to be honed. Most knives don’t need to be sharpened as often, usually just needing a good hone between sharpenings.
Can over-sharpening harm my knife?
Yes, you can sharpen a knife too much. The blade was designed with a proper bevel leading to the edge. Over sharpening can change the angles, and actually make cutting more difficult.
