Oops! Forget to add this picture of an Austrian officer's sword with it's knot.

p.s.-  The Poles used cavalry but left their lances home for parades. Not  being fools, they usually parked their horses and fought on foot with  machine guns and rifles. They did do a sabre charge on a German  encampment and  were very effective, coming out the other side they  heard armoured vehicles approaching and wisely left.
The  Germans widely used horse for transport of personnel and supplies,  wounded, etc.. They were forbidden to film them in action tho, as hitler  wanted everyone on the allies side to think they were all fully  mechanized. They actually used almost twice the number of horses they'd  used in WW1. especially when they started running out of gasoline and  diesel. The Italian Cavalry also made a number of successful cavalry  charges against the Russians.
