I had alsways heard it as " You don't need butter knives if you have
putty knives"


Scroll saw will do extremely detailed work in stock of moderate
thikness (1" or less)

Bandsaw is limited in the radius of the curve by the depth of the blade
but will cut much thicker stock.

You can back out a cut in a scoll saw, try the same thing with a
bandsaw and on mine the blade falls off the drive wheel.
