Engineering tools to replace Hammer/Arclight Spanner

Hey all,
I keep reading on wowhead about certain tools like:

  • Gyromatic Micro-Adjustor replacing Blacksmith Hammer and Arclight Spanner
  • Or Arclight Spanner replacing Blacksmith Hammer

Neither of these are true, as I have found with crafting engineering items that required a combination of the aforementioned tools.

Are there are tools that actually replace the Blacksmith Hammer or Arclight Spanner?
