EDC for my essentials:

• Gerber Dime multitool - includes pliers, scissors, box opener, flathead, bottle opener, tweezers. Can alternatively hold a Leatherman Micra or Squirt, but may not be as snug a fit.
• Wera Zyklop 8001 - Tiny ratchet
• Removable holder for 10 x ¼" screwdriver bits
• Extension Socket - For harder to reach places/easier finger screwing/drill use
• ¼" socket adaptor - To use ¼" sockets
• Cards - I fill mine with 4 debit/credit/ID cards and 3 business/loyalty cards.

All tools are magnetised in place to stop them sliding and jumping around. This requires 10x5x2 bar magnets for the ratchet and multitool (one each), and 3mm diameter 2mm deep magnets for the ¼" bits (one each), extension socket (1 or 2) and ¼" socket adaptor (2).

There's a textured version of the main holder, purely for aesthetics.

Bit holder can be inserted either way into the main holder to either keep the bits accessible in situ, or lock them in extra-safely facing inwards. It can also be used by itself if you want something slimmer.
