Review on TISUR Titanium Keyring with Side Pushing Design - Stylish Men's Accessory in Keyrings & Keychains by John Arsov

This item is easier to use than regular split key fobs with a rounded profile. The end slides easily to the side and the low profile makes it a great option for small openings. The price of these little devices is a little high, but they are worth considering as an alternative to the open-end wrenches that break nails.
