  • Who do we need so many different kinds of saws?

Acceleration/Previewing/Vocabulary:
Rip Saw, Cross Cit Saw, Back Saw, Dovetail Saw, Coping Saw, Hack Saw, Aviation Shears, Tins Snips, Lineman’s Pliers.
Teaching Strategies and Distributed Guided Practice/Summarizing Prompts:
  • Rip saw and crosscut saw
    • Crosscuts are used for cutting across the grain
    • They have a more teeth then rip saws.
    • Why do we want to have a lot of teeth for crosscutting?

    • Rip saws have less teeth and cut with the grain
    • Think of a table saw.
  • Backsaw
    • Used for crosscutting
    • Why does it have a metal backbone?
    • To keep it stiff
    • Helps keep the blade stright
  • Dovetail saw
    • Used for cutting dovetails
    • They are more precise then a backsaw so it is easier to make more precise cuts.
  • Coping Saw
    • Use for cutting very intricate shapes
    • Can be used to cut external and internal cuts
    • Can change the blades for finer cuts.
    • Used to cut moldings
    • The blade can be taken off easily for cutting inside holes.
  • Hack Saw

    • There is a compound lever to make it easier to cut the metal it takes less force to used then the tin snips
    • They were designed during WWII for women who were working in the factories.
    • Why are there different handles Red for left hand curves green for right hand curves.
    • Tin snips are also to used to cut sheet metal
    • Made for cutting straight lines
    • They are just like scissors.
  • Lineman’s Pliers
    • Also called combination pliers
    • They are used by electricians
    • They are used for cutting and bending wires
    • They can bend the wires perfectly for outlets.
