Ceramic vs. Premium Steel Blade

What is the difference? 
We get this question a lot from our customers, as our Furzone A5 blades have two different materials: Premium Steel and Ceramic.
Here's the introduction of these two materials' characteristics:
  - Using exceptional Japanese high carbon steel 
  - Chrome-plated for rust resistance
  - Can be sharpened and reworked


  - Using high-tech ceramic
  - Cool running and reduce heat transfer
  - Intended to keep extra sharpness for longer life


Depending on the user experience, some think ceramic blade does a better job of staying cool and sharp for a longer period; whereas, some think steel blade can be sharpened, which can extend the product life.
