Whether you need to light a fire in the woods or just open a letter at the office, our EDC Kit 2 has you armed for any occasion. Every day carry (or EDC) refers to a small collection of pocket-friendly tools that you carry with you on a daily basis for tackling situations both mundane and – when required – disastrous. The idea behind EDC is to keep the kit streamlined with an eye towards self-reliance — you want items that do the most, while taking up as little pocket space as possible.

Our EDC Kit 2 turns your keychain into a productive tool, wherever you may be. There’s a pressurized pen for filling out declaration forms at 35,000 feet, as well as a compass for finding your way in the middle of the wilderness.

The quick release brass key ring allows you to easily give your car key to the valet or hand off your house key to the housesitter. Corrosion resistant and rustproof.

The stainless steel perforated folding knife is mirror polished with a clip-point blade. Made in Italy with cutlery-grade 420 steel, which resists mild acids.

The brass compass has a Lexan lens and is water- and shock-resistant. Glow-in-the-dark background for nighttime navigation.

The stainless steel key chain pen has a pressurized ink cartridge so you can write at pretty much any angle and at high altitudes. It’s only activated with pressure, preventing the ink from leaking.

The brass key chain flashlight with glass lens delivers a high light output of up to 235 lumens (that’s almost three times more than a camping head lamp).

The magnesium fire starter features a high-carbon steel blade. Magnesium shavings ignite even damp tinder and kindling easily but are fireproof in solid form.

The stainless steel key chain carabiner opens and closes with a brass screw clasp. Accommodates over 10 keys or EDC tools. 


Use & Care

Each of these tools can be attached to your keychain. Part of their utility means that they require little or no maintenance, and they are useful in any number of situations. 

All items can be attached and removed from the stainless steel key ring carabiner. For full product information on the individual items, see the separate pages for the stainless steel perforated knife, brass compass, brass key chain flashlight, quick release brass key ring, magnesium fire starter and stainless steel key chain pen.

Your EDC kit is intended to accompany your travels. Kaufmann has never had a customer report any trouble of bringing their EDC kit through airport security or TSA.

Production & Design

The companies that make these keychain tools were founded as far back as 1948. Most are family-run businesses that source materials from the U.S. and assemble the products in America. One maker even supplied the International Space Station. In other words, you’re in good hands with these tools by your side.
