Abstract
A cutting blade made of surgical stainless steel with a very small angled back hone, a small grind angle, a small angled front hone, and a reduced size included angle, which has an increased hardness that results in a longer lasting narrow edge geometry blade that has a reasonable cost with increased durability and accuracy, providing greater cutting precision, productivity and net yields, while reducing the compression of the blade and processing downtime.
