Spike 1? Edge 3? Level II/Spike 1 combination? Whether you are in a correctional environment or out on the street stab vests are some of the least understood safety equipment public safety professionals have.
Here we discuss: why stab proof vests really aren't, what the difference between Spike and edge threat ratings is, what the different (1,2,3) energy ratings mean, and how stab vest ratings were created.
In US jails and prisons "shanks" & "shivs" are the primary threat. Jailers, Booking Officers, Jail Guards, Correctional Officers, and support staff of all varieties are wise to utilize stab vests or correctional armor to give them a leg up.
It might not be as sexy to talk about complex Joule ratings and testing procedures instead of shooting at ballistic armor but it is important for those who rely on stab armor to have a realistic expectation of the level of protection it provides.
