When you pull it open to 90 degrees, you can lift it up to reveal the first latch; fully opening it to 180 degrees will reveal the second latch, allowing you to adjust it based on your personal needs. The keychain knife has a hole at the end, which can be opened to fit onto a key ring for easy carrying.
