Backsaw

Backsaws

Backsaws have a stiffener along the top edge which helps to keep the blade straight and allows for closer control and fine work.

Tenon saw	- the most common backsaw, typically 250mm or 300mm length with 10-14 Teeth per Inch (TPI) and used extensively for general woodworking and fine cutting of joints such as tenons.
Dovetail Saw	- similar to a Tenon Saw but shorter at 150mm to 250mm with finer teeth at 14 to 18 TPI and used for finer work such as cutting dovetail joints.
Gent's Saw	or Fancy Backsaw - typically 150mm long with very fine teeth (16 to 25 TPI) and used for very fine cutting of mouldings and inlays for example.
Razor Saw	- commonly approximately 125mm long interchangeable blades with extremely fine razor sharp teeth (i.e over 50 TPI) and used for fine work in balsa and plastics - e.g. modelling.
