The KeyBiner was originally designed by Chris Mioduszewski from Fortius Arms in Aluminum, Titanium, Brass etc. We fell in love with the design and its usefulness so we decided to alter it a bit to make part of the Brous Blades family. The CF Keybiner is a more refined version of the carabiner many use to carry their essentials every day. The biggest change was the addition of a unique key retention system, which allows you to keep your keys neatly organized and quiet. We also added a smaller version of our BMT with several tools to aid you in your daily chores. The CF KeyBiner has no sharp edges to cut you or damage your clothing. Screws and hardware are included so you can custom fit the key retention to hold as many keys as you need. It can carry up to 14 keys depending on shape, size and orientation. The design is attractive, extremely durable and manufactured 100% in the USA.
