Dede loves the ceramic over the ultra edge but she uses them all. The ceramic is not metal to metal so it's heat factor still there but it gets hot slower. It still gets hot, any friction of tools will get hot but it will just get hot a bit slower than the ultra edge. She uses all blades though, oster the same.
Ceramic = only can sharpen about 5 times and no more sharpening life, gets hot less fast, cuts like butter
Ultra Edge = sharpen almost for years and have life on the blade, gets hot faster than ceramic.
