Here are some recommendations for quality metal key chains:

Titanium key chains

Made from durable, lightweight titanium. They have a subtle shine and come in different shapes and styles.

Stainless steel key chains

Also very durable and resistant to corrosion. They come in a variety of finishes like brushed, polished and matte. Some have fancy engravings or logos.

Aluminum key chains

Lighter and softer than steel but still durable. Aluminum key chains tend to be more affordable.

Brass key chains

Highly corrosion resistant and tarnish resistant brass. They naturally develop a shiny or patina finish over time.

Leather straps with metal attachments

Adding leather straps to your metal key chain can make it more comfortable to carry and add a stylish touch.

Keysmart key chains

These organizer style key chains have multiple loops to store various keys and other keychain items in an organized way. Many are made from metal, aluminum, titanium or steel.

In terms of brands, many people recommend brands like KeySmart, Skeletool, Kuson Key, Zero Grid, Machine Era and Marble’s among others. The key is to look for high quality metals, secure attachments and strong craftsmanship. Japanese, German and Swiss brands tend to have a reputation for such craftsmanship.
