Whetstones are the most traditional and popular way to sharpen knives. So if you prefer whetstones over electric and manual sharpeners, then this handy step-by-step guide is just for you.

First of all, Choosing Your Whetstone

If you don’t have a whetstone and want to buy one. There are few things you need to take into consideration.

As a beginner, you should look for a double-sided stone. One side should be 6000 grit, and the other side should be 1000 grit. Keep in mind that the lower the number is, the coarser the stone gets.

When you increase the grit, you will get a sharper knife blade. however, it requires extra strokes.

Step 1: Wet the Stone

 Most whetstones need to be soaked in water before using. We recommend soaking 45 at least, or till there are no air bubbles on the water surface. and then put them on a dry towel.

 If you own a stone fixer, then you should put it in water as well.

Step 2: Adjust the Angle

This step is considered to be the most difficult one. Yesm it is difficult, but not impossible!

 There are just a few things you should know before setting the angle. First, smaller angles will result in having sharper edges. however, these edges will not be so much durable.

While bigger angles will do the exact opposite. giving a less sharp blade yet a durable one.

Second, the easiest way to sharpen a knife is to place it in a position between vertical and horizontal, which is from 15 to 20 degrees angle.

Finally, you should maintain the angle throughout the process to end with a good sharp shape. Any change in the angle could be dangerous and may result in damaging the knife blade.

Step 3: Sharpen the knife

 It is preferable to start with the lower grit first. after adjusting the angle, start to sharpen in a back and forth motion.

The pressure comes on the back motion while dragging the knife. It’s better to start with the side that is closest to the handle and end with the edge point.

Step 4: Finsih a Stroke and Repeat

 Every time you reach the end point of the edge, this counts as one stroke. You need to repeat the strokes till you feel that the knife blade is sharp enough.

Step 5: Look for Silty Water

After multiple strokes, you will see silt water over both the stone and the knife. This liquid means that you are one the right track.

Step 6: Check the Burrs

 Seeing burrs is a sign for you to head to the other side. It should take from 30 to 40 strokes per side to get these burrs.

If you don’t want to over sharpen your blades. then 10-15 strokes will be enough.

Step 7: Sharpen the Other Side

Wet your stone and knife with drops of water, maintain the same angle and repeat.

Remember to end the stroke with the tip of the knife over the near-edge of the stone.

Step 8: Switch the Stone

 If you have a complete set or a double-sided whetstone, it’s time to use the finer-grit one, whether it is separated or in the same whetstone.

Step 9: Repair the whetstones

 After many strokes, you will see grooves in the stone. So it’s always recommended to buy a stone fixer. All you have to do is to put the stone fixer against the whetstone stone, then push it back and forth.

 This motion will result in creating a new flat surface thanks to the grinding part.

Having grooves on the stone will hinder the process and delay the effectiveness.

Step 10: Clean up

Place the stone and knife over a towel to dry thoroughly. And keep in mind that the grit doesn’t come out with the towel.  So, try to make a special one for this purpose.

Step 11: Hone your Blades

 The final step in sharpen a knife is to hone your knife using a honing steel to have an alignment shape.

you can test the sharpness of your knives by cutting a hard tomato or chopping onions.
