But you need to know the right ways to use this technique, otherwise, you will end up with two damaged knives.

  3. Adjust the knife angle you are holding in your right hand at a 20-degree angle against the first knife.
  4. Move the blade of the first sharper knife away from your body with a stroking movement. Maintaining the same angle during the sharpening.
  5. Turn the knife on the other side. And repeat step 4.

The Second Way

Steps

  1. With your right hand, grasp the knife that you need to sharpen. While in your left hand, hold the knife that you will use as a sharpener.
  2. Position the blade of the knife you are holding in your left hand downwards.
  3. Adjust the knife’s angle you are holding in your right hand at 10 degrees against the back of the knife you are holding in your left hand. With the blade facing opposite to you.
  4. With a smooth motion, move the knife to stroke the entire length of the blade apart from you. Maintain the same angle of sharpening throughout the entire sharpening.
  5. Turn the knife to the other side. And repeat step 4.

This sharpening method is ideal for hunters and those who use their pocket knife or survival knife most of the time outdoors.

The key requirement for this technique to work is selecting a smooth, flat, and porous rock to use. After that, lubricate it with water. just like a regular whetstone sharpener.

Steps

  1. Take a slightly flat, smooth river rock and wet it down. Even if it is clean, add some water to it to act as lubricating moisture for the abrasive stone.
  2. Turn the knife’s blade so that it is pointing in the opposite direction as you. Set the sharpening angle at 10 degrees and position it on the stone’s surface.
  3. Use a smooth motion, stroke the knife in the opposite direction from you. Ensure that you cover the entire length of the blade. Then, turn the blade and begin pushing it towards you to sharpen the opposite side.

Method #5. Sharpen Knives Using a Car Window

A car window edge is a very successful tool when you are on a road trip. Since the window’s rough edges are not brushed like the remainder of the window, then when you slide the dull blade edge against the window. It will act as a sharpening rod.

Steps

  1. Position your dull blade at a 10-degree angle on the rough side of the window’s edge.
  2. Using smooth motions, stroke through the opening, where the window will serve as a honing steel.
  3. Ensure that you stroke the entire length of the dull edge.
  4. Move the knife to the opposite side of the blade and begin stroking.
  5. Keep the same-degree angle edge. And continue repeating steps 3 and 4 on both edges until you reach the needed sharpening blade.

#Method 6. Use a Slate

If you don’t have a whetstone sharpener to sharpen your western knives or Japanese knives, a slate will get the job done.

Slates are rough enough to permit effective sharpening but not too rough. Find a flat slate that is clean and a little rough (pieces of slate that do not have any special decorations on it).

Steps

  1. Find the proper slate piece and lubricate it with some water.
  2. Adjust the edge sharpening angle at 10 degrees against the smooth surface of the slate. Ensuring that the blade angle faces opposite to you.
  3. Pull the knife in the other way from you in a smooth motion against the slate. Maintaining the same angle edge between sharpenings for the entire motion.
  4. Make sure that you cover the entire blade length of the dull blade.
  5. Flip the knife on the other side. Then repeat the entire smooth motion again.
  6. Make sure that you stroke away equal metal shavings on both sides. Repeat until you reach the sharpness you want.

Method #7. Use a Broken Glass Bottle

The point is that a broken edge of glass bottles is not refined. If you want to sharpen your blade, unpolished slabs of glass are a good option.

The edge of glass bottles can be cut cleanly using a variety of techniques. You can do this with plate glass or a glass clipper.

Soak some string in acetone, wrap it around the part of the bottle you want. Then light it on fire for about 30 seconds, and then immerse the entire bottle in cold water.

Because both use rough glass, the sharpening technique is the same as for the car window glass.

Steps

  1. Find or cut a  broken glass bottle. To get unbrushed edges.
  2. Adjust your knife’s edge at 10 degrees against the bottle top.
  3. In a smooth motion. Covering the entire length of the blade and stroke opposite to you.

If you do not have a sharpening steel in your high end kitchen knife block. This sharpening method is a good short-term solution. especially for your steel knives.

It would be best if you fixed the sandpaper on a piece of wood. to make it more like a customized sharpening stone, ranging from coarse to finer grit.

Steps

  1. Use a piece of a wooden block, fold your sandpaper in a rectangular shape. Then fix it on the block, leaving some space between the sandpaper sharpener and the block.
