When consideration is given to your options for a fixed blade in your survival kit, there is really only one clear choice. Since size and weight will be primary factors in building any type of survival kit, you will want to keep these to a minimum. The clear winner in this department will be the single edge razor blade.
With its small and relatively compact size, negligible weight and extreme sharpness, the single edge razor blade is an ideal choice to give you a cutting edge in your compact survival kit. They’re also flat...which is a good thing.
Single edge razor blades also make a great addition to your first aid kit.
