New Design
for Ancient Tool
Mankind has been using shovels for thousands of years: made of wood,
bone, stone, iron and bronze. But using it has always been
"back breaking" work.
What was
wrong with the old design?
The ones that our grandfathers used require you to bend down and lift
with your back. This is a very painful and dangerous activity
for the millions of us who suffer from back problems.
The exertion also places a great deal of stress on the
heart. We all know people who have died of heart attacks
while shoveling snow. The icy-cold air combined with the heavy lifting
puts too much strain on our bodies.
Still,
the sidewalk and driveway need to be cleared...
