The Ideal Co. makes a tire grooving and siping iron that has simple 
clamping screws on the business end to hold whatever type of knife, 
blades, etc you can fabricate or concoct. I have one of these irons and 
have used it quite a bit for modifying tires. The heat really helps with 
cutting through the rubber.  The best blade for window removal would be 
made of beryllium copper (the strongest of all copper alloys) which has 
very good thermal conductivity.  This is the tool I would grab first for 
cutting out a windshield.
