How to sharpen knives and machetes (double-edged) to restore their sharpness.
If you put the blade against your nail and it slides without getting caught, it's a sign that you have a cutting problem. Place the blade on the whetstone and make sure that the edge of the blade you want to sharpen is in perfect contact with the whetstone. Position the knife at an angle of approximately 45 degrees to the whetstone and place your finger on the area you want to sharpen. Please sharpen lightly without using excessive force. After sharpening approximately the number of times (about 20 times), sharpen the back side the same number of times. Finally, remove the burr and it is complete. After finishing, remove the moisture and let it dry. For long-term storage, wipe with camellia oil or other oil. *If the blade is chipped, a different process is required.
If you want to increase the strength of the blade (for example, when chopping wood), please attach the small blade with the blade upright. That alone will significantly increase the strength of the blade.
Note: The surface of the whetstone should always be flat. As you use it, dents will appear and you will not be able to sharpen it cleanly. Don't forget to look back when you do so.
