If you want to add an affordable, ultralight, and corrosion resistant utility blade to your EDC, Backnife might be for you. Backnife is a polymer utility blade holder that, when paired with a ceramic blade, is completely non-metallic and therefore rust-proof. They weigh just 3 grams and are barely larger than the utility blade itself making them extremely easy to add to your EDC.
Backnife holders are available in multiple colors, with and without ceramic blades. They are available Amazon or direct from Backnife.com.
