What is a bow saw?

Blade
The bow saw has a long, straight blade that can be removed from the frame. It is designed for quick and rough cutting of tree branches and shrubs.
There are two types of blades on bow saws:1. Serrated blade pin
The toothed blade is designed for cutting dry hardwood, not wet.
The teeth on the serrated blade of the pin are triangular in shape and arranged in groups of 3 with a large gap between each group.
2. Toothed pin and rake blades
A blade with pin and tine teeth is designed to cut through wet wood, not dry wood.
This type of blade has groups of 4 triangular teeth followed by 1 "rake" tooth, which looks like a normal tooth split in two and splayed outwards.
The triangular teeth cut through the wood, and the so-called "rakes" split the wood.When sawing wet or damp wood, chips can clog the saw teeth. The serrated blade of the pin and comb has larger and deeper troughs on either side of the combs, effectively moving wood waste out of the kerf.
cutting stroke
The teeth on a bow saw blade are not all angled in the same direction as on some other types of saws. This is because the bow saw is designed for push and pull cutting.
Please note: How this is done depends on the make and model. One of the methods is shown below:
Teeth per inch (TPI)
Blades with pin teeth tend to have 6 to 8 teeth per inch.
Pin and rake blades typically have 4 to 6 teeth per inch.
To complete
All bow saws have large, deep-pit teeth for fast, aggressive cutting in wood.
Because they have fewer teeth per inch, they cut and remove more material per stroke, usually leaving a rough surface.
Processing
The bow saw has a so-called closed pistol grip. This type of handle is commonly found on saws with large or long blades that are designed for faster, more aggressive cutting.
The large handle supports the blade, and because it is closed, the user's hand is less likely to slip out when sawing fast. In addition, the closed design protects the user's hand from injury in the event of a sharp impact of the end of the saw against something.
