Types of Handsaw
Handsaws have teeth cut along the edge of a tempered steel blade, and a handle, but no stiffener along the back which enables them to make long cuts or across wide pieces of timber.
The most common types are shown (from top to bottom) :
| Ripsaw | - used for cutting along the length of boards to reduce their width or produce long strips. Typically they are approximately 650mm long and with 6 to 8 teeth per inch (TPI). The teeth are sharpened at 90 degrees to the blade to to create a chisel action which enables them to cut with the grain. |
| Crosscut saw | - used for cutting acros wide boards and for this reason the teeth are filed at around 75 degrees to the blade to create a knife action. Typically they are approximately 600mm long and with 8 to 10 teeth per inch (TPI). |
| Panel saw | - a shorter version at about 500mm long and usually with crosscut teeth around 10 to 14 teeth per inch (TPI). They are used mainly for cutting sheets of thin ply to size. |
Handsaws remain useful for general work especially on-site. They are now stamped out of steel alloy sheet with hardened teeth such that they tend to be replaced when blunt rather than sharpened. In the workshop they have largely been replaced by Bandsaws, Table Saws, Mitre Saws, and Circular Saws.
Safety Point! Woodcutting machinery is extremely dangerous and must only be used by adults who have received appropriate training.
