Guy argues that the flail we all know and love, mostly from D&D never was used in battle. He makes a number of points.

Let’s look at the evidence.
Firstly, as a weapon of war, the flail is not a good design. The element that makes a flail unique—its chain—is the biggest drawback. The chain and swinging ball make this theoretical weapon extremely difficult to control. In a tightly packed formation, a swinging weapon would be as likely to brain your fellow soldiers as it would your enemies. If it were to rebound, say off a shield or even a successful strike, it would be likely to hit you. God help you if you miss, and hit yourself or the thing flies out of your hand.
And in terms of physics, the swing certainly gives the metal ball a higher speed than the head of, say, a similar mace. However, the mace, being rigid, allows the fighter to follow through the swing with their whole body. Any follow-through with a flail would just make the potentially disastrous rebound hit you even harder. Also, the chain is a weak point that could break or be broken by your enemy, or find itself wrapped around their sword, or the handle of a larger weapon.
“But wait,” you may ask, “what about those flails at the Met that you just mentioned?” This is where the story gets interesting. My working hypothesis is that all the flails at the Met, and those in similar collections occasionally found elsewhere in the world, are, as Warner asserted so bluntly, fakes.
I call this a hypothesis because I have not (and likely will never) examine every single one. And, the possibility that fakes can exist in museum collection sets many curators’ teeth on edge. The art world has acknowledged (and even occasionally celebrated) the fakes in their museum collections for decades now. But history museums have been far slower, generally quietly correcting their catalogues rather than taking this particular bull by its horns. To their credit, due to the questions over their provenance the Met no longer displays their flails in the museum.
I looked at the Met’s flails with the help of Dr. Nickolas Dupras, an expert in medieval arms and armour.
This one, Dr. Dupras, says, takes its form from a horsewhip (a “goad”) instead of a military weapon.
“The chains look relatively flimsy,” Dr. Dupras said, “these three-ball flails are based on manuscript illustrations depicting early ‘cat-o-nines’ or whips, also depicted as instruments of torture in Passion and martyrdom illustrations.” It’s important to note as well that a real goad would have been made of wood and rope—why this one, a copy of the form, is made of steel is unclear.
The next one in the Met’s collection is very different, with very fine workmanship.
The flail is not a weapon so much as it is an icon. It exists, and will continue to exist, because it so vividly paints the Middle Ages not as it was, but as we believe it to have been. That the medieval military flail exists at all is probably the most fascinating thing about it.
