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

This item is easier to use than regular two-piece 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. While the price of these little devices is a bit high, it's definitely worth considering as an alternative to the open-end wrenches that break nails.
