Which of the following types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
hacksaw |
|
crosscut saw |
|
rip saw |
|
coping saw |
Wood saws are categorized primarily by their teeth. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
