Just use the biggest loop (the one immediately right of the fob in your pic), and cram everything you need on it. You can toss the dual bottle openers, if you need two you need to reconsider your drinking situation. Get a small Leatherman multipurpose pocket knife if you need something with versatility. I stopped keeping mine on my keyring, when I really thought about it I didn't use it often enough to justify the hole it helped wear into my pocket on two pairs of pants. lol Don't hang any decorative/trinket crap on your keychain, no one cares what your name is or what brand car you drive or that you like turtles. The less you have on the keychain the less of an annoyance it can be.
I just have 2 keys and a small usb thumb drive (I do computer work for a living). We have a code access front door and garage lock on the house. I've also gone minimalist on my wallet, using one of those small security wallets and no longer carry cash. If anyone reading this is thinking of going with the less-is-more route, then you're probably already there. I was 'thinking about it' for years and have zero issues/regrets after streamlining things about 3 years ago.
I just keep it simple. Car key and the fob for my exhaust valves, which I just leave in the little pocket by the armrest. Garage door is programmed and the inside door is coded so no house keys needed.
Not sharp, but I have raised some metal in very small spots. The fob is soft metal for sure. The KIA logo gets rubbed against other keys and turns to crap. Mine isn't as bad as at least one other Stinger fob I've seen a picture of on here.
