I wish I saw this topic in time. I pull tons of glass at work. I have used so many things wire, the "windshield knife" that you posted a pic of,long shaft urathane knife and the excaliber (sp) but nothing works as good as the inductive coil units. A bunch of companies make them and we were able to rent one for a week for $100 to see if it would be worth buying. It was. With 2 people you can have a windsheild out in 15minn or less.
