The Compact Folding Survival Bow, or CFSB-1 for the acronym happy (I think the "1" indicates it's #1 in the world, like America or Megan Fox in a Supergirl outfit), is a patent-pending one-piece takedown bow milled from T-6 6061 aircraft grade aluminum and fitted with fiberglass bow limbs. According to vendor Primal Gear the long bow that bends and tucks into a 23" short riser is the only folding bow on the market designed with survival in mind.
CFSB-1s have removable limbs for easy replacement, interchangeability with different draw weights, and so that the bow converts quickly from right- to left-handed use. The included limbs have draw weights as follows: 47 pounds at 26"; 52 pounds at 27"; and 55 pounds at 28". Arrows fire at average speeds of 181 feet per second.
When open, the Compact Folding Survival Bow extends 59" long. It weighs just 2.25 pounds for carrying in/strapping to most any pack or bug out bag. According to Primal Gear, this bow is built to "survive the apocalypse, put food on the table, and defend you when you need a silent and powerful self defense weapon." Provided, that is, you know how to hold, aim, and fire a bow.
