The Best Ultralight Keychain Tools

These are the most durable ultralight tools I have found. They all fit on a keychain:

  • Titan Plus — very durable construction — produces 300 lumens of light — as much a bright full-sized flashlight — waterproof — made in USA
  • i3E EOS oLight  — tiny waterproof keychain flashlight — 90 lumens — uses a single AAA battery
  • Nite Ize Inka Pen — writes underwater, writes in temperature from -30 degrees to +300 degrees — ultralight — made in US
  • Quick Release Keychain Clip — ultralight titanium clip for keychain
