Due to the brittle nature of the knife’s blade, placing much pressure on the blade by way of sharpening it can cause it to break easily. Instead of just holding the knife at the handle and trusting your applied pressure to do a good job, consider placing as many fingers laterally on the blade instead. Do not expect to press hard and then come out with a sharp knife. What you would most probably end up with is a broken blade. Lightly pressing the full blade on the diamond whetstone is enough technique to sharpen your knife without any casualties.

Porcelain blades do not give that burr that is ever so common with sharpening the other knives. The sharpness of the knife highly depends on the technique employed in sharpening it. Swift movements using little pressure is the way to go about it. That way, even without the burr, you can be assured of a good job done.

There are other materials you can use to sharpen your knife but diamond is the most preferred. There are electric knife sharpeners, but in getting one, it would be expedient to make sure that it can cater for a ceramic knife before purchasing it.
