I bought a set of T Handle Philips screw drivers when I bought my 1977 Honda 750k and thier is a difference. I still have them but did recently strip a screw on my RSMV when installing my carb covers with a standard screw driver. I didn't have my T Handel with me (bike is stored 300k from me). I learned my lesson on that project ! Yamaha does show T Handle Tool Set
