I'm interested, thank you. Seems strange that it lasted such a short time (unless of course it was made in China with a "lifetime guarantee").
I can't imagine wearing a steel bullet proof vest through a metal detector!
I have not ever tried cutting Kevlar. I've read that bullet proof vests are not particularly knife proof, I believe Kevlar has great tensile strength but did not realize it might resist cutting.
"The bottom line" - great choice of words for this particular issue.
