Sterling Systems Pocket Sharpener

This is a very small and flat pocket sharpener made of stainless steel with a tungsten carbide wedge.

To use the sharpener just place it on a flat surface, a table, a rock, a tree branch etc and then slowly slide the edge of the knife downwards through the carbide wedge.

With almost no pressure and a few passes any respectable knife will be razor-sharp, if the knife blade was very rough you may need some extra passes or apply some extra pressure. The sharpener is very gentle with the edge without leaving marks or creating dangerous dents.

As small as it is you can put it almost anywhere and it will be unnoticeable, a very recommended companion if you frequently use edged tools.
