I like to use the 'demolition grade' blades. They ll cut wood, metal, plaster, wire, or pretty much anything you d care to throw at them. They're made from decent carbon steel that will take and hold an edge rather well. When bought in packs of a dozen, they can be had for about a buck each.
The bandsaw blade is what actually makes a cut in the workpiece, or item to be cut. Typical bandsaw blades have hooked teeth which cut material away from the workpiece. Other styles of blade include grit edge and slicing, or knife edge, types of blades. The bandsaw is the machine which carries the blade. It includes the wheels and motor for turning the blade, and a table or other fixture for positioning the workpiece and moving it into the blade.
