I realize that it has no importance in most cutting tools, except maybe for scapels used in delicate surgery, like eyes, and I think lazers are what are most in use now.
When a knife is sharpened, the edge is something like a V, and where the two lines converge are what makes the edge. One difference in the shape of the V would be what some refer to as an appleseed shape, where the sides are rounded until they converge. What I am trying to find out is how broad this spot can be and the knife be considered sharp.
No importance, yes, but I figure that knowing is better than not knowing.
