Cutting edge up
A katana is displayed edge up on a horizontal stand, which comes from a samurai wearing his katana edge up and on his left side, so that he can draw his katana with his right hand and cut downwards. Besides, there will be no pressure on the cutting edge in this displaying way.

Handle to left
When you face a displayed katana, if the handle is pointing to your left, it means there is no hostile or threatening attitudes as the handle cannot be drawn with the right hand.

Handle to right
When you face a displayed katana and the handle is pointing to your right, it shows an aggressive and guarded attitude, as the katana can be drawn directly from the stand with your right hand and respond to any immediate attack.

Display a katana in scabbard
The general way of displaying a katana is to keep the blade within its scabbard.

Display a katana out of scabbard
Displaying your katana without its scabbard expresses your aggressive and guarded attitude. The handle of your katana should point to your right.
