There's no governing body proclaiming this the world's smallest crossbow, but it's only slightly larger than a full-sized crossbow arrow so it's got to be up there. Joerg designed this crossbow to be safe. The arrow is fully encapsulated so it won't accidentally shoot off in an unexpected direction.
You cock the crossbow with strong rubber and it's the right length for the tip to stick out. That way the crossbow can accommodate all different broadheads and unload safely. It's 1.5 lbs without an arrow in it. And Joerg gives it the Slingshot Channel seal of approval: "Ideal as a backup crossbow!"
OK, you heard the man.
