Best knife sharpener
I've had half a dozen of these over the past 10 years to sharpen Global knives, I also found it more cost effective to buy the whole product again rather than buy spares.

not so great
My knives were pretty blunt and this eventually started to sharpen them but took far more effort than suggest and even without overpressure I broke a wheel on my 5th knife. Replacement wheels pretty expensive. Bought a different knife sharpener with instant success. This one may work better with knives that are not as blunt as mine to start with.
