Woodworker creates beautiful pieces despite blindness

For more than 30 years, John Cook has created masterpieces from scratch. But, he never sees the finished product.

"My hands are my eyes," says Cook, "I can see imperfections, unevenness that your eyes cannot see."

Cook lost his sight to glaucoma when he was just a kid.

"My accuracy is actually better than the human eye," says Cook.
