I was thinking about one of these pocket sharpeners?
Blade Tech Knife Sharpener, which uses tungsten carbide to sharpen
blades.

Its going to be used mostly with my camping kit to keep my Opinel razor sharp, but would be usefull to have something small to handle my bigger kit like a Axe or billhook?
Any thoughts or recommendations STW?
