 All knife and sword blades have a point of precussion somwehere along the blade.  It is the point at which the sword mass is centered, and where the maximum amount of force will be transferred.  I would suggest that a skilled user would be trained to deliver powerful blows with that portion of the blade;  and, as long as the point of impact occurs there, the vibration and shock transmitted to the user would be minimal.
