Any recs on a BIFL key chain? Those rings always get bent over time, looking for something sturdy. Might just be a flaw in the design because if you can bend it enough to get a key on, you can probably bend it out of shape over time.
A little late for a reply, but I use stainless steel 16-14 gauge rings made for chainmail and use pliers to bend them open and closed. The Ring Lord is where I get my material for projects, and then I just use the rings for keychain stuff too.
I use an S-Biner keychain. https://a.co/d/7nuHlqm
Let’s you take you’re yubikey or thumb drive off your keychain eff effectively infinitely without it wearing out.
I use one of these to attach my yubikey to my keyring.
Idk about secondary key chain rings, but I use a chain link with a screw thread as my main ring. Have been for 20 years or so.
This is what I use also. I made a little Paracord fob for it to jazz it up.
I have it separated with a few rings so I can remove just my car key or house key.
Very late to the game. I use this guy, 10/10
Would using a small carabiner as a key chain meet your needs? They can be quite stylish and are sturdy by design.
