Okay, so today I bought a new pocket knife and it is ceramic. The manager of the store I got it from said every once and a while just cut a plastic water bottle. He said that the plastic from the bottle helps sharpen it. But I'm not sure if I'm buying it. What is the best way to sharpen my knife...and a way that I don't have to pay an arm and a leg or a sharpener for something? And my last question is can I use a strop on it?
 
Wow, that is so wrong! You must be very careful when cutting tough material like plastic! The blade is very brittle and can chip or break. You must always cut straight. Pushing or pulling through a material is okay, but never twist while cutting - you could chip or break the blade.

The only way to sharpen ceramic blades is with diamonds. The good news is that the ceramic is extremely wear resistant, so shouldn't need to be sharpened for a very long time (unless you get a chip).
 
You could use a strop loaded with diamond compound, but you don't need to, as the ceramic should not develop a burr during sharpening that would need to be removed on a strop.
 
That guy saw you coming.


Sharpen by cutting plastic bottles?, ...PT Barnum was right.

I had a feeling he was wrong lol but thank you!
 
You'd have to use diamond sharpeners.
Also..plastic bottles? I hate to say it but he fed you a load of crap. You're right in not buying that.
 
You don't. You use it until it dies, or you send it back to the factory for them to resharpen. And then you never buy a ceramic knife again. :D
 
Nice thread. Thanks for the input.

My wife has a very oooold Kyocera paring knife used many times every day.

I just sliced a thin slice of tomato (now).

You can see the blade through the slice like you see the blade on the cover of Botoroff's book. Sharp enough without a strop for 5 or 10 years.

wazu013, thanks for the link. I had not known that.

one of the mods from the boker forum sent me a butter knife dull ceramic folder several years ago so i can see if i can sharpen it. i managed to get a good working edge on it but i am not done with it yet. i have small diamond disks that i put on my dremel and they work great. i have not tried the finest disk i have yet but it already push cuts typing paper. i have ran the edge over the paper grit wheel to see what it would do but i should have tried the grit wheel before i sharpened it on the diamond disk.
