Our house is a bastion of old windows and truly decrepit glazing. I knew sooner or later I would need to scrape away whatever remains of the window putty. That time came sooner after I accidentally broke a couple windows. I ordered the Prazi Putty Chaser which I had seen months ago at Duluth Trading. The device has a simple design with a carbide bit at the end. You just set the depth for your window with a simple set screw and then attach it to a power drill that spins 2000-3000 rpm. The device works as advertised and makes short work of old window putty. In fact, it even ate right through the metal glazing points. However, the bit can be tough to control, and you definitely need a fast drill. It did do pretty well with my small projects, but I am not sure I would trust it to major jobs. FYI, the manufacturer’s site doesn’t behave well with Safari or Firefox if you are on a Mac. It suggests you “upgrade” to Explorer or Netscape and freezes navigation:

I bought mine for about $20 at Duluth Trading
