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
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
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
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
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.
LED keychains are a great tool to have and use. They are bright, last a long time, and lightweight. LED lights have come a long way since the early days, and now we can see LED lights in so many places including businesses, electronic, and even flashlights. However, I’ve also seen some other cool keyring tools like a really neat Flash Key that was in the shape of a real key and fit on a keyring. I thought it was really a key, but when the person stuck it into my computer I was shocked. It looked really cool and worked well.
