Sharpening Ceramic Blades???

[presenttc]

I have two Boker kitchen ceramic knives. They seem to need sharpening faily often. I sent one of them to Boker for resharpening and payed $18.00 for the sharpening.
Now it's dull again.
Does anyone have any suggestions on how I can sharpen these ceramic blades myself?
Many thank,

g'day mate,

I have a boker forder in ceramic. I chipped the edge 2 yrs ago and have been trying to resharpen it ever since. I have at DMT duo's, DMT Aligner Kit in 4 grit, Lansky type rig diamond in 3 grit, EZlap, and numorous natural and synthetic stones, and you know what? I am still trying to resharpen the blade!!

I can rebevel the edge, but when I try to the edge, all I can get is a serrated edge.

I think they use a diamond belt to resharpen the edge. Maybe someone with experience will chime in.

A friend of mine talked someone he works with into getting one of the Boker ceramic pocket knives. He tried sharpening it on a diamond steel, and said it wound up cutting through the diamond steel.

I've been wondering if you could sharpen it if you do it backwards. You know, normally we draw a blade across the stone like we're shaving off a thin slice. I'd like to try dragging one from spine to edge sometime and see if I could make any progress that way. It'd probably take a long time, though, and it'd probably have to be diamond.

Yes you need a finer abrasive, even the 1200 grit dmt stone is too coarse. DMT sells muxh finer diamond paste which I will be trying shortly.
