The GDC Hook Knife is designed to lives on a keychain and can be used to quickly cut yourself out of a piece of clothing, seatbelt or other safety strap, should you ever get stuck in a tight spot.
Seat belt is not 100% safe, in some accidents, victim just got stuck on seat belt – so at that critical moment, you just need something to cut the belt off and you know that seatbelt is pretty tough (some mechanic even use to pull up an engine). So if the unlucky who got stuck, this GDC Hook Knife will be handy. But if you were to compare, of course it is safer to use a seat belt than not to use.
$11 each and backed with Gerber’s Lifetime Warranty.
