I have several pieces of glass I need to replace in some double hung,
double pane vinyl windows. Each pane has four vinyl strips which holds
the pane in place. I use a painters tool to remove these strips with
no problem. The other side of the pane is caulked (with silicon) which
holds it to a half inch vinyl casing. What tool is best to use to run
between this casing and the window to cut away the caulk? It looks
like some kind of sharp blade with a 45 or 90 degree angle would work
best. Any experienced window people out there have any suggestions for
the right tool? Thanks in advance.

If you haven't already located a tool, I'd recommend an artist's
palette knife. They come in several different styles, some of them bent
like you describe (or with an offset handle), and in several different
degrees of stiffness. Wouldn't be difficult to sharpen the working edge
for better cutting, but then I do that all the time to other edged
tools. YMMV.
