It will break the window but it will also wreck your tip. Glass is harder than steel and because a knife tip is so fine is will just get bent or broken. I tried it with an old Benchmade just to find out and I blunted the last 1/8" of the blade.
The glass beaker on the 3Mil is just a semi sharp little nub that's big enough to not get damaged but small enough to still break the glass efficiently. Just hit the window in the corner.
You won't damage the RC5 tip breaking a car window-that I can guarantee. It's at least as thick as most glass breakers.
