This is a very sturdy product. I locked my left thumb in to see how they feel. It comes in a little vinyl pouch with a belt loop too, but I just hang it off my Level 2 vest for a just in case situation.
Has some nice weight to it as well, I wasn't expecting such a strong locking mechanism.
-KS has the coolest military surplus of anybody!
