Global knives need a different sharpener than other knives because they have a different shaped blade edge – they're much thinner. Whilst regular sharpeners will do the job, they cause Globals to lose their unique edge. The Global Ceramic Water Sharpener keeps that edge intact, just sharper.
And it's an easy process : water goes into the sharpener, and half a dozen passes in each of the slots sees the knife sharpened by ceramic wheels. You'll still need the occasional professional sharpening session, but the Global Ceramic Water Sharpener will keep your Globals effortlessly slicing those tomatoes between sessions.
