BTW: Those V-shaped or single sharpeners with small pieces of super hard tungsten-carbide metal are evil.

They don't sharpen but scratch, plane away whole layers of metal from the knive blade. They are brutal and gruesome. You can use it for the blade of a lawn mower, but don't do it with good kitchen / hunting knives!

Ok, maybe outdoors on a trekking tour for emergency use, when the knife or axe is really damaged and you need a quick basic sharpening...
