A family member stuck the blade of this knife into my window, so that burglars couldn't open the window and break into our house. It worked so well that I can't open the window or get the knife out.

The handle of the knife is almost flush with the window, so I haven't been able to get a grip on it. This was during the summer. Now that it has gotten cold I suspect it's even more wedged in.

Any suggestions on how I can extract this thing?
