JIS screwdrivers are 100% necessary. It may seem PH fit at first, but it's _a tiny bit off_ enough to cause damage. The point of JIS is shorter and squared.

Thanks for the kind words! The ifixit screwdrivers I linked are JIS compatible.

The PH-0 and smaller screwdrivers from Good suppliers like iFixit or Wera are actually JIS because there's no downside.

But if you happen upon a real PH-0 it will destroy the JIS screws.
