Hey Krystina,
Ceramic knives are very different. You don’t want to use the coarse grit stones unless absolutely necessary and they’ll never get super sharp like steel does, they’re just too brittle and won’t hold an acute angle without chipping. When you do ceramics, you won’t be able to draw a burr, ceramic doesn’t behave that way, so the best way to make sure you’re reaching the edge is with a marker, checking to see that all the marker is removed by the stones. Light pressure is imperative. You can use the strops and finer pastes/sprays to greatly improve the edge quality. If you have a loupe or magnifying glass, you can inspect the edge for chipping – from there you can decide if you need to put in more time with the fine strops.
Clay,
I have followed your instructions above and cannot seem to get these Kyocera blades razor sharp!?! They were very (VERY) dull when they came to me; the progression I went thru is as follows… 100/200, 400/600 and then 800/1000.
Never did pull a burr at start (w/ 100), thought maybe since ceramic, burr would not form?
Shall I go (back) to 50/80?
I believe my pressure is OK… not too light.
THANKS–
.
