In an apocalyptic situation or you are just out in the woods without a sharpening stone, there are many ways to sharpen your knife or axe without one. In this Instructable I will show you a few of them.
Step 1: Car Window
If you are near a car and you can get the window down, just run your knife along the unpolished and rounded part of the glass on the top of the window. Do 3 or 4 passes and flip your knife, repeat until sharp.
Step 2: Coffee Cup
If you flip your coffee cup over there is an un-coated rounded edge that will work the same way as the window works.
Step 3: River Rock
A flat, rounded, and smooth river rock will work almost as well as a real sharpening stone. Just use it like you would use a stone, because it is one...
Step 4: Stropping
Once you have a nice sharp edge you will need to strop your knife.
The nylon straps on your pack work well,
A leather belt/ sheath will work too.
Just hold the strap tight and run the knife along it backwards.
Step 5: Thanks
