Is there some reason you need a wide kerf? They make "scroll saw"
blades for jig saws, I have some marketed by Craftsman (don't know who
makes them), 12 tpi, 3" length, .165" wide, .06" kerf, retail $4 (Sears
Milwaukee makes a narrow blade that works OK for scrolling, but is a
rough cut: 4" long, 6 tpi, .25" wide, .075 kerf (Mil. #48-42-5010).
Both are T shanks.
These are just the blades I have on hand. Bosch tends to have the best
selection, and their CS is good: have you given them a call to ask if
they have the type of blade you're looking for? I would be surprised to
find that VA made a blade that Bosch didn't.
I mention this because the best jig saws out there now are pretty much
all T shank, they aren't that expensive and will serve well in so many
