Nylon Straps

To sharpen a fixed blade knife, you can use a nylon strap. First, fold the strap lengthwise and place it on a flat surface facing up the folded side. Then, pull your knife back down the bottom of the top edge at an angle, removing material from both sides of each blade serration. 

Something as simple as the strap of a backpack is more than enough to sharpen your survival knife. First, move the blade away from the cutting edge by rubbing it against the nylon strap.

  • Hold the strap securely in place so that it is taut.
  • Run the edge of your knife across it a few times.
  • If you aren't careful, you can easily cut the strap if you aren't paying attention.


Coffee Mug

A coffee mug is probably one of the essential household items for sharpening a knife.

If you wish to use a mug, make sure it's ceramic and has a highly glossy bottom. Because you will only be using the bottom of the cup, it makes little difference if the sides are glazed or polished.

After you've chosen a mug and determined that you don't mind getting a scratch on the bottom, it's time to sharpen your knife with it.

It's not difficult to do, and the more you practice, the better you'll get. Hold your knife at a twenty-degree angle to the bottom of the cup with the blade. Run the blade along the bottom of the cup slowly and lightly, precisely as you would with a sharpening stone. If your blade is exceptionally dull, a coffee mug might be an excellent way to remove many materials. 


Aluminum foil can be used to sharpen survival knives like full tang, but you need to take care not to cut yourself. You should use the aluminum side of a sheet and fold it lengthwise into one long strip about as wide as your survival knife blade. To sharpen knife blades using these features, place the metal under your knife at an angle to remove the from both sides of each blade serration. Again, be careful not to cut yourself!

Bicycle Inner Rims

If survival knife blades become dull, the knife may cut through bicycle inner rims. Bicycle inner rims are steel and can be used as a makeshift sharpening surface for survival knives. Hold your knife at an angle against the rim with just enough pressure so that it is cutting into it without slipping.

Spark Plug Insulators

Spark plug insulators are another option for survival knife blade sharpening. They're made of ceramic, which is harder than steel and will make the survival knife sharper. For this hack, simply place a spark plug insulator on top of the knife at an angle so that the material is taken off both sides of each serration.

Ceramics in Fishing Rods

Ceramics in fishing rods are a great way to keep your survival knife blades sharp. Ceramic emits electrons, which can help remove metal from survival knives. Simply place the ceramic inside the knife at an angle and run it along each serration while applying light pressure.

Semi-Precious Stones

Semi-precious stones are another way survival knife blades can be sharpened. Like sandstone and quartzite, these stones will make knives sharper because they're harder than steel. Run the survival knife along with a semi-precious stone at an angle with just enough force to cut into the stone without slipping.

Another Knife Edge

Another reason to carry a second knife is that you can sharpen your knife blade using the edge of another knife. This is pretty effective, and you only need two knives.

Just a heads up: it won't be as cool as you've undoubtedly seen in movies and TV shows. When some cool broody guy sits on a rock and scrapes two knives or swords together, sparks fly everywhere. If you get sparks while sharpening your knife using this procedure in real life, stop and figure out what you're doing incorrectly.

Hold your second knife in your non-dominant hand and the knife you wish to sharpen in your dominant hand to sharpen your knife using this method. Run the blade of your survival knife at about a twenty-degree angle across the spine of your other knife in smooth and steady motions.


Dog Leash

Tying a dog leash around your survival Knife and securing it to a stationary object is another survival knife sharpening option. Just pull the knife back and forth against the leash while applying pressure.
