I'm a belt newbie. I have only used one ceramic, one zirconia, and several AO belts so far and none of my belts have been retired yet.
My experience was that the zirconia only performs well at high pressures, much higher than what seems useful for blade grinding though it works great for notching and shaping because the pressure/psi is so much higher. The ceramic works well but seemed to lose its original sharpness fairly quickly. It does seem to last well, but at this reduced cutting power during most of it's life. The AO belts seem to cut well for their whole life, which is admittedly short in comparison to the ceramic, but I think that so far I like the AO the best on a cost/performance/life basis. I guess I will try another ceramic when I order belts based on what Bruno said above, but the zirconia will not be reordered.Last edited by bluesman7; 07-22-2015 at 04:24 PM.
