This is a Double Slap Tower Laceration/Iwasawa Tower
This is my hardest trick ever, it is extremely hard and challenging to do. Polo inspired me to do this as he did and landed it at his 2017 Asia Pacific Yoyo Championships finals routine. This is a really cool yoyo trick as well.
The yoyo used in this video is the Smashing Yoyos Interlagos.
