Just ordered a Boker Gamma88 which has a ceramic blade. first one for me. How do you sharpen these when it is required?
 
From what I have heard of these blades, you almost can't sharpen them yourself. Not sure on that though.
 
Your going to need Diamond hones to acheive proper results with Alumina Ceramic blades. I have 2 Ceramic bladed knives from Maddog and use 600 grit then 1200 grit EZlap stones per Maddogs suggestion and can achieve excellent relsults. Bear in mind that your not going to ever achieve a shaving edge with your knife, the only way to sharpen them is with the diamond stones which cause a micro-serration of the edge. It will slice like the devil but shave it won't whatever you do don't thin out the edge bevels it will make your edge fragile and it will chip just cutting cardboard If you need further help feel free to email me.

My guess would be sand paper. Now I'm not sure about that one...might work though.

What was I thinking:rolleyes: . Must've been another knife I was thinking about. Sorry
 
I consider all this to be a downside....what is the point in getting a ceramic knife then?

The point of a ceramic knife is that the ceramic is the hardest material next to diamonds. So it last a LONG timeif used properly.
 
Ceramic blades can be sharpening to a shaving finish, you just need a fine stone. The diamond pads only go up to 1200 grit which isn't fine enough. You will need to use DMT paste which goes down to 1 micron.

Just received response from Boker... "Please do not try to sharpen the blade yourself." Send it to them for 11.95 including shipping and they will do it in 3-4 weeks.

Sounds like they're probably making more money sharpening knives than selling knives.

I can't help but question this kind of official response. If they've got something that can sharpen ceramics, I can get something that will sharpen ceramics.
 
JamesA makes a good point. I'll see if anyone else knows what it is that sharpens ceramic or wait until I see how long it takes to need to be redone. thanks for the input.
 
We are knife folks talking about knives. Boker's statement is for the vast number of non-knife savvy households who own STEEL kitchen knives and probably don't know how to put or keep an edge on them.

My house was always like that when growing up. We always had turkey that was hacked to peices from using kitchen knives as sharp as butter knives. I didn't know any better as a kid.
