About 50 cm in length, the Stand is bounded to a Napoleonic-era dagger (around the end of the 18th century and the beginning of the 19th century.) The dagger itself has a straight double-edged blade. The blade is symmetrical and shines much like a mirror. The hilt has a decorative pattern on it.
Partial Damage Reflection: Whenever the user takes damage, 70% of that damage is transferred to whatever is reflected on the blade of the dagger, while the user still receives the remaining 30%. Gunshot wounds and even virus infections can be transferred.
The Stand can not only reflect attacks from others, but inflicting one's self can also direct the damage to whoever is reflected in the blade. The damage that is received is in the same location of where the damage was dealt. The damage that is reflected is not what was dealt physically, but rather "the level of damage" that was received, i.e If a man in a suit of armor attacked, and his attack was reflected, the amount of reflected damage he would receive would be irrelevant to how well his armor can defend against physical attacks.
