Just a question about the yokote (line at which the point begins) on the japanese style blades. Is this line always present, or were some tanto and swords made without it? From an article by Bob Engnath and from his web site, the line isnt present on some styles of tanto, but seems to be more common on sword points, although its not always there. Also, I understand the straight angled tips common now are a modern interpretation that is rarely found on traditional blades. Just checking what I think to be true.
