For climbing purposes, the carabiner is perfect. It does a job and it does it well. When it comes to carrying your keys, however, the carabiner could use a little retooling—and that’s just what happened here. The Mehlville is a carabiner redesigned for your everyday carry. The dual compartment design means your keys are stored securely and never at risk of slipping off without you noticing. There’s even a thumb stud bottle opener so you can crack a few cold ones without adding an opener to the mess of keys you need to carry around. Each is machined from a solid block of aluminum and finished with stainless steel details. It’s not going to break; it’s not going to let you lose your keys; and it will look great in the process.
