The inventor of Kevlar died earlier this week.

Were APSers aware that the weave for bullet-resistant kevlar and puncture-resistant kevlar are a) entirely different and b) offer almost no crossover protection?

Dept. of Corrections tried to go cheap and bought semi-sorta-nealy expired Level III vests for COs to use as protection against shankings.  Took two near-fatalities and one lawsuit for them to "discover" the difference.

Add to that the weave for cut-resistant items (gloves, sleeves) is whole another kettle of fish.  I can attest that properly-worn cut-resistant gloves will save yur fingers from a commercial electric slicer.

The easiest to construct stuff using kevlar seems to be logging chaps.  Pretty much just long strands oriented vertically, designed to catch & jam the chain.  Saw someone put a set of chap to the test.  Messy as all get-out (strands all over the place besides jamming the chain) but worked like the charm they were supposed to be.

stay safe.

Had a guy prove a good cut resistant glove by smacking me across the palm with a sharp blade hard enough to leave a bruise through the glove.  Proved a cheap one to my old boss by cutting it into little pieces with a not-very-sharp pocketknife.
