In our “Buy It For Life” posts we feature products that are built to last a lifetime. We also give preference to products that are very durable, are warrantied for life, and are made in the U.S.
The Fenix LD01 is barely large than the AAA battery it uses (we recommend using a low-discharge rechargeable NiHm AAA battery). It is very bright — it produces 80 lumens on its highest setting, which is brighter than most full-size flashlights.
The Fenix LD01 is solidly built — it 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 also RoHS compliant — it does not contain non-toxic heavy metals or flame retardants.

Leatherman Micra Tool
Leatherman Micra is a keychain-sized multi-tool that contains a total of ten tools, including a pair of scissors. The Micra weighs 1.6 ounces, and it’s 2.5 inches long when closed. Leatherman tools are guaranteed for 25 years (10 years for their lights). Specifically, the company says “we will gladly repair or replace it, at our discretion, with one of equal or greater value”. Over 120 buyers on Amazon, rated it an average of 4.5 out of 5 stars. The Leatherman Micra is available on Amazon for around $20.
Another good keychain-sized multi-tool is the Gerber Shortcut Mini-Scissor Tool.
Arc-AAA LED Flashlight
Designed for keychains, Arc-AAA flashlights are barely larger than the AAA batteries they contain. The exact dimension are: 2.5 inches in length, 0.5 inches in diameter, and 0.75 ounces in weight. The Arc-AAA is made in Phoenix, Arizona by Arc Flashlights. The company only makes keychain-sized flashlights, and put a lot of attention into the design of their lights (see the FAQ page of all the technical details).
The Arc-AAA is warrantied for life against manufacturing defects. It features a Nichia white LED light, and is waterproof to 100 feet. I’ve used this flashlight for about five years, and I’ve never had any issues with it. It has fewer scratches on it than my other keychain lights, perhaps due to its “Type III Hard Anodized 6061 Aluminum” casing.
The price is $29.95 for the standard model, and $44.95 for the premium model Arc AAA. It’s available directly from the manufacturer Arc Flashlights. There’s also three titanium models available that range in price from $125 to $140.
We like this flashlight because it’s made in the U.S. with a lot of attention to design detail. It’s also slightly smaller than the Fenix LD01 (below). However, the Fenix LD01 (see above) is much brighter than the Arc AAA, producing 80 lumens, which is quite bright for a keychain-sized flashlight.
