Hi Banjo
The wider the blade the straighter the cut , a Pull saw should be the best hand tool . Coping , Fret , & Piercing blades for curved work , A bandsaw is most universal power saw in a workshop with blades for 1/8" to 1/2" ( 5/8") on some small ones. If i had to only one powersaw it would be a small to mid size bandsaw eg, Delta, Kity"woodster", or Rexon.
