Most people in the world are right-handed.
Most of the products are made for those people.
So, left-handed products are rarely designed.
Right-handed products are not universally designed.
I would like to introduce to you the first concept of universal
design in this presentation. It is a cutter knife for both hands.
Existing knives have only straight switch, but this knife has
a wheel switch which makes it easy to draw out the blade.
so, when we use it for left hand, it is safer because, it has
a cover on its upper side of the edge.
With these methods, left-handed people can use the cutter
knife safely.
