The Keyrabiner 4.0 is here – and it’s more durable than ever! When creating the 4.0 model, we wanted to enhance the thin, lightweight features of the 3.0 Keyrabiner; however, we really wanted to apply some of the durable and easy-to-use features we loved about the classic 2.0 Keyrabiner.

By upgrading the fundamentals of what we and our community love about this insert, we’re able to create the best Keyrabiner yet! Each individual Keyrabiner is made of pure titanium. The functionality is designed to act like a carabiner and can fold into the KeyBar for convenient storage. To ensure complete quality control, each Keyrabiner is crafted with our water jet right here in the USA.

  1. I use this to connect a small victorinox. Super easy to use and functional carabiner!

  2. A perfect little device that is light and tough. I was worried it would easily break or not retain it’s shape, but that isn’t likely to be a problem. I live how easy it is to connect to my car keys and how it’s profile is small enough to be unnoticed and keep everything held close together—no annoying dangle!

  3. Nice little add on that really doesn’t get in the way even when folded in. It’s nice to be able to have a spot to clip on an additional ring of keys, fobs or whatever else that I don’t want in the clip itself but still want easy access to.

  4. The unfortunate things about keys are fobs, at least for the majority of people out there. This little device makes management of the fob easy, highly recommend adding this to your purchase to finish out your product.
