Keychain MEGA Micro Bit Kit (pt 3)

Here's the last entry of my three part series on how I fashioned a tiny multi-bit screwdriver for my keychain out of a sawed off Lutz 4-in-1 pen screwdriver. This video's MEGA micro bit kit makes it a 46-in-1 KEYCHAIN screwdriver! World's smallest! {and probably the only one too, ha-ha.]

Psst: I forgot that a reverse 4mm bit acts as a 4mm Allen wrench so the grand total in "sneaky" mode is 52, not 51. Only certain bits fit in this mode and some drilling of the pen cap was necessary. It was a tight fit and not recommended. My advice is to stick with "46-in-1".

The bits for this were taken from two "master kits" I leave back home due to their bulk. The double-sided bits are mostly from a "Powerbuilt 940506 30-In-1 Flexible Extendable Precision Screwdriver" and the single sided are from a "Precision Screwdriver Set - 108 in 1 Mini Screw Driver Magnetic Multibit Screwdriver Small Electronics Repair Tool Kit for Watch/Cell Phone/PC/Drone/Eyeglass Repair" [the name changes slightly depending on vendor]. Both sources cost around $16 and can be found on Amazon, etc.
