My favorite tool set to read the full text >>

In daily life, there are often occasions where small tools and flashlights are needed. I like this small combination most.




The Swiss Army Knife is not introduced. This model is my favorite. It has very few features, such as a big knife, a knife, a beer bottle opener, a can opener, a wine stopper, and a drill awl. The other is a few small screwdrivers, tweezers, toothpicks and so on.


I like this knife because it is small, it is very functional, it has all the basic functions that are needed in daily life, and it can maintain a reasonable size. The "championship" function is more, but the volume is really not flattering. I will never bring it to the streets. When it is needed, it will naturally be impossible to use.

The ARC flashlight is a product of Arc Flashlight LLC of the United States. It is known for its superior quality and compact shape. It is recognized as the best micro LED flashlight in the world.

The barrel material is aviation-grade aluminum, and the surface treatment is natural gray-green HA III (three-stage hard anodized coating), which is currently the best surface treatment process with high wear resistance. At least for so long, I was wearing a Swiss army knife.


ARC brand flashlights have excellent water resistance up to 30 meters. The Internet is said to be 100% waterproof at 100 meters.

The feeling of use, its brightness is not very high, online data is 2 lumens, after all, only a battery, and a single LED lamp. However, this also gives it a good lighting time performance, and another famous SUREFIRE L4 is also an LED lamp head, using two CR123A, the brightness has reached an astonishing 60 lumens, but the time is reduced to a short time of 75 minutes.

Therefore, ARC "AAA" is suitable as an auxiliary lighting, when looking for a key during a power outage, reading a book at night, and looking at the stairs inside a staircase.

There are three versions of the ARC “AAA”, the regular version before 2003, and the whole body black; the regular version after 2003 is changed to gray-green and has a higher hardness; the LE version in 2002, which is a limited edition, has a white lap in the tail It is said that the LED lamp is hand-selected, whiter and brighter, but the online commentary and my own view is not the case, see the following section. As shown in the figure: From the top: the regular version before 2003, the regular version after 2003, and the LE version in 2002 (note the trail of a circle).

The ARC "AAA" has different grades of the same model, mainly the lamp level, Standard (standard), number AWS-NAT; Premium (optimum), number AW-NAT, using SB1 Nichia LED, color temperature is more White. The 2002 ARC AAA LE (Limited Edition) uses AW-NAT level LEDs.

Buying advice: First of all, you should know that the price of ordinary type is about 200 yuan, and the price of LE is probably 100 yuan more than the ordinary type. The LE type is exactly the same as the post-2003 version of the regular AW-NAT type. Therefore, LE quality can be purchased at a normal price. The method is to look for gray-green, and indicate on the outer package: "AW-NAT White LED Natural Case". This is what I bought

In addition, when buying, take a few more comparisons, open them together, shine on a white paper at the same distance, pay attention to the color and focus of the spot, be careful not to buy the lamp is awkward, this kind of beam focus is not good The spot is obviously not correct.

Turn an article on a loudly motivated forum SXR:
The Arc-AAA LED flashlight was the winner of the 2002 Lummie Award for "Best LED Flashlight" and "Best Portable Flashlight for Everyday Life". It uses a cheaper AAA battery, ordinary alkaline batteries can be continuous light for 5 hours, more economical and convenient. Small size, can not be on the key ring, or with a pocket clip on the pocket; Aerospace aluminum tube type III anodized hardened plating surface treatment, than the type II flashlight used in the torch is expensive, anti-scratch effect is more it is good. 50ft/15m deep waterproof design (tested 340ft/104m 100% waterproof). The inner walls are treated with ChemKote to enhance their corrosion resistance.

ARC-AAA is Arc Flash's first flashlight product, which uses a super-light LED bulb, small size, easy to carry and use, and aluminum barrel greatly reduced the weight of the entire flashlight.

Arc Flashlights had long noticed the market demand for LED light sources - at that time, they did not use low-alkaline LED flashlights, but all used lithium batteries. Arc Flash uses a new converter to make the 1.5 volt standard AAA battery also provide enough energy to support the LED light bulb, even brighter than many LED flashlights with multiple AA batteries!

One ordinary AAA battery can emit light for 5 hours continuously. Moreover, when the battery is exhausted, the flashlight will automatically switch from the standard “daylight” mode to the more dim “moonlight” mode. This mode keeps the flashlight on until it continues to glow. Running out of all the battery power will not waste the battery, but also provide a longer light time, to remind you to replace the battery.

Turn the flashlight clockwise to turn on the flashlight; turn it in the opposite direction to close. Inside the barrel there is an o-ring seal that guarantees 3 feet/0.9 meters deep waterproof. The end of the tube has a snap ring that allows the torch to be attached to a keychain or hook.

The surface of both the torch head and the barrel body is sanded to ensure that it is stable under all conditions. In addition, a foam pad was added to the bottom of the torch head to eliminate the buzzing sound from the impact of the battery and the barrel head.
