Know Your Metals
All our key rings have the same design—circular body, integrated bottle opener, slot for attaching to belt loops or pockets—but the prices and materials are very different.
We believe every object tells a story, and the different materials (in this case, metals) have a huge impact on how that story evolves.
Stainless Steel • $39
This was the original key ring material. We use an alloy that is popular for its high strength and corrosion resistance, and treat it with black-oxide to create a black finish. The stainless steel key ring feels substantial in your hand—it’s pleasant to hold and to use. It’s softer than titanium, and still virtually indestructible. It’s the bedrock of our key ring collection, the quiet and strong type.

Alloy - 330 stainless steel
Density - 0.289 lb/in3
Hardness, Brinell - 150
Brass • $59
Brass is bright and attractive, and even more than stainless steel, it carries a substantial heft. Brass has long been a popular metal due to its workability and durability. It’s a majestic, even monumental, metal. We polish each key ring until it glows before it leaves our workshop, and it develops an attractive patina over time.

Alloy - 360 brass
Density - 0.307 lb/in3
Hardness, Brinell - 144
Titanium • $79
Titanium is the most expensive metal that we use for our key rings. It feels magically light, but it’s incredibly hard. In fact, it has the highest strength-to-density ratio of all known metals. It’s completely corrosion resistant, and has excellent biocompatibility, making it essential for surgical applications. It’s notoriously difficult to machine, but our friends Scott and Taylor at STS Machining weren’t afraid to roll up their sleeves. It’s a magnificent, lustrous, metal. We stamp each key ring with its elemental symbol, Ti, to denote its value.

Alloy - Ti-6Al-4V titanium
Density - 0.16 lb/in3
Hardness, Brinell - 334
