No, you're thinking of Zylon. Zylon has greater strength, but isn't as effective over time. Actually, studies are showing that Kevlar is stronger over time.
My advice is Kevlar mixed with shear thickening fluid, about 8-16 sheets of Kevlar one on top of the other, to help catch the bullet.Unfortunately, Kevlar can stop bullets, but not knives.Knives slide right through Kevlar like butter, the threads almost "make way" for the Kevlar, and thus the knife slides right past the layers, and into YOU.This is where the SHEAR THICKENING FLUID comes in.This liquid (which i believe is a silica base [don't quote me on that!])Is just a bunch of molecules floating around in the Kevlar like a liquid should? Right?But when you apply kinetic motion (i.e.: knife stab) the molecules form a practically unbreakable lattice that only deforms when kinetic motion is no longer applied, so in essence, you can stab and stab, and stab, and you won't be able to break this.This also strengthens Kevlar's ability to handle speeding projectiles.This has been tested, I can't quite remember the source, but i do remember that they [researchers] dropped a huge knife (seriously, this thing was HUGE) from 8 feet, or 243.84 centimeters, equivalent to a 220 pound force, or 99.7903 kilograms.It barely made a dent. A dent nonetheless, but still not very much.They tried some other test, mainly involving a MASTER ARCHER, and a BOW AND ARROW.Keep in mind that this was a STEEL TIPPED ARROW, fired at a shear thickening fluid/Kevlar set of sheets.The tip of the arrow, the STEEL TIP bent.This guy fired it about 187 miles per hour, or 300.947 kilometers per hour.It was only a dent, slightly bigger that the first, falling knife test.In all, if you're shot, it will hurt like h-e double hockey sticks, and it will bruise, and/or break your bones.But this will DEFINITELY keep you alive.
P.S: Kevlar has been known to degrade due to UV radiation (sun rays), and infrared radiation (heat), so use a thin layer of NOMEX (the material firefighters use)
P.P.S: I haven't updated my profile pic in 4 YEARS, so sorry about that.
DISCLAIMER: These facts were from a documentary, of which the credibility I cannot prove.(Although I think it was PBS, or NOVA.)I don't know whether the shear thickening fluid will dry, seeing as it’s a LIQUID, nor if it has any negative effects on humans, or Kevlar, as this material is still in prototype stages.In any case, substituting/adding ceramic plates might help, like the ones they use in the military.
Thank you for your time and patience for reading this article,

huh, must've been a text glitch, when i copied this over from word (it has better spellchecking) sorry for the no spaces.
thin vests might stop the bullet but you still get the effect of the bullet even with police vest it bruises and hurts. not sure on plates . so not perfect but better than a shirt
you can get yards of Kevlar material online easily. using felt as an internal liner and an external compression layer to soften the blow you could do it. I would take a watermelon put the felt on it, put the layers of Kevlar on it, put your compression layer on it, then shoot it with whatever iiia iii or iv caliber from about a foot away. if successful I would replicate and add double the layers of Kevlar.
The only reason I would give such foolish advice is that I want to do the same thing for the doors and back of my pickup as a bug out vehicle. I have a professionally made iiia stealth vest. I want to look innocent while extracting through check points.
Buy your vest and make anything that you want to save that they wont sell you.
Also I have a pair of tactical pants where they have a knee pad that's replaceable. I am going to make a pair of iiia knee pads that wrap around. a leg wound is one thing but a knee injury is for life.
I recently read an article about how you can make Boron Carbide, (which is what they use on tanks, and is much, much stronger than Kevlar,), from an ordinary cotton T-shirt. If you have access to an oven that can get about 1300 degrees fahrenheit, that could be a relativity cheap way. http://news.discovery.com/tech/gear-and-gadgets/t-shirt-body-armor-tank.htm
I have personally dealt with a company called AR500 at www.AR500.com
They are great. Their product are legit.
