Combination saw and knife

Fig. 37

Materials you will need to make the combination saw and knife are:

One broken hacksaw blade between 12 and 14 cm long

One piece of wood

Length: between 10 and 12 cm

Circumference: between 9 and 10 cm (as measured by string)

One nail, 5 cm long

Saw

Drill

Making the Combination Saw and Knife

The piece of wood is cut along the length of the stick as shown in the following diagram. The depth of the cut should be equal to the width of the blade.

Fig. 38

Drill a hole with a small diameter in the middle of the stick as shown. The broken hacksaw blade is inserted into the slot until the hole in the blade is lined up with the hole in the wood. The nail is then inserted. Bend over the nail which sticks out of the other side.

The edge of the blade that does not have teeth should be sharpened on a hard stone or with a file. You now have a tool which can be used as a knife or as a small saw.
