Katori Detail
The area of the kashira, where the left hand holds the wooden sword, is shaped to be slightly domed (like that of a live blade mounting). It is cut with a cleanly delineated edge and formed by the action of many little cuts of a razor sharp knife.
This wooden sword is not used with a guard (tsuba). It's length is blended smoothly from tsuka (hilt) to the blade section rather than having a step or relief transition at the position of the hand guard.
 
On the left is the chisel style point of the Katori Bokken. The strong geometry of the chisel point bokken lends to the weapon's trueness of form with minimal embellishment. For information on how these weapons are made, see this link - About Kingfisher WoodWorks
