The 5 yo-yos that revolutionized yoyoing

Thanks @YOHANS and @Gentry_Stein 1904 St. Louis World’s fair yoyo (1904, first patent) Flores yo-yo (1926, first looped string yoyo that spins) SKF Swedish (~1965, first bearing and take-apart yo-yo) YYF Grind Machine (2004, first unresponsive yoyo) Shutter (2013, wide but smooth spinning, broke price down to $50 for metal yo-yo) I guess this is also @yohans answer to Pick five yo-yos to demonstrate yo-yo history from 1950-2019?
