I'm learning new things as I continue refurbish work on my Blue bike. I never knew the metric screws on Japanese bikes used a different type of Phillips head.

I've been using my regular Phillips head drivers without any issues but like everyone else I abhor the prospect of the unnecessary disfigurement of fasteners.
