How To: Sharpening Without a Sharpener
THE RIVER ROCK
Have no fear; there are many ways to sharpen and hone your knife in the field without a proper sharpener. Granted, you should never leave the house for a camping trip without something like a trusty Work Sharp Field Sharpener. But alas, it happens. Take these steps to bring your edge back in the field.
Begin by determining how dull is "dull." If it wouldn't cut warm butter, you need to scour the area for a rock with a relatively smooth surface. Look in creek-beds for one that has been smoothed by water. Chances are, you will be able to find a rough-grained rock that has enough of a flat spot where you can draw your blade over from tip to tang. If your stroke is "into" the edge, just make sure the apex isn't catching too hard on an uneven surface. If it is, draw the knife away from the edge (backwards). Do this until the edge reaches an apex. Then move to something finer.
THE CERAMIC MUG
A favorite "fine-grit" solution is a ceramic coffee cup. The underside of the cup will have a ring where there was no glaze when the cup was fired. This exposed raw ceramic is fine-grained and will produce a keen edge. If the ceramic seems to get clogged, add some water and let it create a little slurry. This will make it sharpen even better.
THE CAR WINDOW
Another go-to is the edge of a car window. The edge is sanded and has a frosted appearance. This extra fine abrasive is just enough to hone and knife and bring it back to "sharp." Granted, this method only works if you are car-camping.
THE LEATHER BELT
Finally, your belt is a good substrate too. Find some fine sand or clay soil and wet a slurry onto the belt. Draw the knife backward, making sure not to roll the knife. Laying the belt on a flat table will help. Don't press too hard, and be sure to make the same stroke over and over until you reach the apex.
