Very nice little sharpener

This is a very good little sharpener. Portable and discreet enough has already been taken for a pen, given the size and the form that is understandable. It is used very well for straight or slightly curved blades (without teeth), but it should not be too damaged blade. Works very well with the Swiss knives or with my Leatherman Charge TTI and fits well in the belt pouch.
After use the blade shaves his problem without arms but we are still far from a real razor sharp, that said it is not the purpose of these knives.
It is not suitable for tools with very wide blades such as axes.
