Be warned though Phil, this style of tungsten carbide sharpener, eats through blades. You can literally see the metal peel of the blade as you pull it through.
A friend of mine bought one (not this one) for his Gerber Paraframe. I bought the same knife a year later which is when we started talking about sharpening. He gave me the same warning and to demonstrate this, he showed me his knife to compare with mine. I couldn't believe the difference, almost half the blade had been removed, it looked more like a filleting knife!
