Detecting Defective Mattresses - 2009 Finalist

2009 Finalist

SAHA (Saw). Finland

Problem:

Ordinary bow saws are difficult to carry and lack proper blade shields. A solution has been found in collapsible saws, but up to now these have been difficult to open or hard to use.

Development:

Experimenting with different shapes, firstly through sketching, then progressively through wooden and metal prototypes, an ergonomic and functional form was found that allowed the saw to collapse as desired, and yet maintain its full functionality.

Solution:

SAHA is a foldable bow saw that can be opened from its storage position within the body of the saw to the cutting position in one swift motion. In the folded position, the saw can be easily carried and is only a few centimetres longer than its blade. The mechanism is also easy to adapt and use with different blades.
