blades available for reciprocating saws vary in length and type. There are different attributes of the saws themselves, and so there are many different variables that can change the nature and purpose of your saw.
* '''Fine Blades:''' Generally used for cutting metal; however ferrous metals (metals which contain iron) necessitate using finer blades than non-ferrous metals (metals which do not contain iron)
* '''Coarse Blades:''' Coarse blades are used for cutting wood
*Cordless models are rated up to 18 volts.
* '''Stroke Length''' and '''Strokes per Minute''': a good combination of these two factors will give you a cleaner, faster cut. Stroke length refers to the length of the cut, while SPM refers to the amount of cuts per minute.
* '''Variable Speeds''': usually trigger controlled and is good when cutting various materials.
** '''Orbital Setting''': some models have the option to change between straight reciprocating cuts and orbital cutting, which is useful when cutting different materials. This is especially true for wood framing as the orbital setting can vastly increase the speed of the cut.
* '''Blade Clamping: '''When switching blades, it is important to turn off the saw and disconnect it from its power source before removing the curent blade. Some saws need tools, such as allen keys, in order to remove a blade. Models that don't need such a tool are known for having a ''tool-less blade change.''
