According to rosewood @FSU, after The Ice 2016 Mao changed her blades from Pattern 99 Revolution to the single plate blades designed by Takahiko Kozuka.
Some info for those who haven't heard of those blades yet: Takahiko designed them a couple of years ago. He conducted a research on how to improve the blades to make them lighter and more durable. The blades he designed are cut out from a single block of metal (while normal blades are cut from two and held together with bolts). Takahiko used them in competitions during his last seasons as a competetive skater. Here's his best performance while using them: https://www.youtube.com/watch?v=bnqHYxIp1gc
