These color-coded hex tools are proof that Japan is living in the future.

I'm currently watching the local darts league. No way those would be allowed.

Oddly, the standard metric sizes are 0.9 and 1.3mm. No idea why these tools are slightly different, nor why there's a random Phillips head. I assume excellent reasons, however.

@jmorris looks like there's a JIS for hex head tools that defines 0.89mm as the tighter tolerance tool, so that's probably it. Given that it's probably also not Philips, but instead the JIS flavor.

@jmorris yep, and looks like it's ~0.02 mm tighter than DIN/ANSI specs. So I'd bet these are JIS ;)
