Here’s a MetaEfficient Keyring. It’s a collection of lightweight, mini-tools suitable for carrying on a keyring.
The keyring contains the following elements:
- The LD01 Flashlight by Fenix (powered by a hybrid rechargeable AAA battery)
- The folding waterproof Inka Pen
- The 6-in-1 Key Ring Tool by Swiss+Tech
- An Emergency Cash Holder by Cash Can
Here are the details of the MetaEfficient Keyring elements:
The LD01 Keyring Flashlight by Fenix
Fenix Keyring Flashlight Powered by AAA Battery
Why It Was Chosen
The Fenix LD01 is the brightest keyring-sized flashlight that runs on a standard AAA battery. This means it can be powered by a hybrid rechargeable AAA battery. It produces 80 lumens of light on its highest setting.
The Fenix LD01 uses a Cree Q5 LED as its light source, and the lens is made of toughened, anti-reflective glass. It weighs 1.6 ounces, and it is “IPX-8 water proof” meaning it is suitable for continuous submersion.
The flashlight is RoHS compliant (meaning it does not contain non-toxic heavy metals or flame retardants).
It’s available for $35 from Amazon.
The Inka Pen
- The Inka: A Waterproof Keyring-Sized Pen
Why It Was Chosen
The Inka Pen is a keyring sized ball-point that can be used quickly as a half-sized pen, or unfolded into a full-sized pen. Using a pressurized ink cartridge, the Inka Pen is waterproof and write at any altitude or temperature. It’s made in the U.S. and has a lifetime warranty.
The “6-in-1 Key Ring Tool” by Swiss Tech
- A Keyring-Sized Multitool by Swiss Tech
Why It Was Chosen
The “6-in-1 Key Ring Tool” is a keyring-sized multitool by Swiss Tech. It contains the following:
- straight knife blade
- a serrated cutting surface
- a micro-sized screwdriver
- a Phillips screwdriver
- an eyeglass screwdriver
- bottle opener
The tool weighs 0.5 oz. Given its size, it’s pretty basic, its handy when you have nothing else available, but not suitable for everyday tasks.
The Mini Cash Can
The Mini Cash Can: A Keyring Sized Emergency Money Consealer
Why It Was Chosen
The Mini Cash Can is an emergency cash holder than fits on your keyring. You can secret a single bill inside this stealthy container. If you forget your wallet, you have the cash inside as a back-up. The Cash Can’s assembly cannot accidentally come apart as long as the keyring is through the hole. The container is waterproof.
I actually found a little difficult to fit a bill inside the Mini Can — the larger Mini II might be a better choice.
