Parts of a Hand Saw

Handle Back Blade Toe Teeth Heel

Saw Terminology Kerf – the width of the blade. You must

account for this for each cut that you make. The blade is 1/16”.

TPI – Teeth Per Inch – The more teeth there are per inch the smoother the cut that you will have. It ranges from 40-120 TPI.

Cross Cut Hand Saw

The blade has alternating

teeth that allows the blade to slice through the grain like a knife.

Can also rip a piece of lumber.

Rip Hand Saw

Reasons for different lengths Torque vs reach

The shorter the shaft of the screw driver the more torque the user will have

The longer the shaft the less torque but more reach

Screws vs Nails Screws have 300 times more holding

power. Threads cut into and deform wood to hold tightly. Can be removed easily

Nails grip with friction hold and will loosen when wood shrinks. Once nails are entered they can not be removed easily
