My layup schedule has a layer of Kevlar on the inside waterline to waterline from the bow to the fin keel. It is intended to give some impact protection. Don't use it on the outside because if you sand into it while fairing you are SOL. There is no way to bury the fuz without putting more glass on top of it.
I tried all sorts of expensive specialty Kevlar shears with no luck. Found that what works best is a $12 Fiskars searated blade shop shear from Home Despot. The secret to cutting Kevlar is to keep it stretched tight. I have two pieces of 2x2 covered with duct tape about 5' long. I lay the Kevlar out flat on the table and lay one 2x2 across it in front of the roll and clamp it down. Then clamp the other just past the cut line while pulling the Kevlar tight. As you cut with the Fiskars, pull back slightly as the blades close. You can cut a intricately and cleanly as you want between the 2x2s.
BTW, for cutting regular glass of all weaves and weights nothing, and I really mean nothing, does the job as well as an Olfa Rotary cutter.

I can second that in spades. It makes a super clean cut and is so easy. Never am I going to have sore hands from cutting glass again (and never again will my wife complain when all the scissors magically become dull)
