I wonder if it is possible in some way with gyroscopes. Not going all the time, but spun up quickly, to provide counter resistance for a specific direction of rotation. You could spin up two, in opposite directions, to counter the torque from acceleration. Difficult to spin them up fast enough, but perhaps just the sensation of some resistance would be enough feedback.

Interesting idea. However, would that create an unnatural, 'valley of the uncanny', type feel? Approaching realism but falling short and ultimately distracting?

I believe this is what Blade of Honor (Tsurugi) did, though I can't find any deeper reference to the controller.

More ambitious idea: Make the controller a grip on the end of a robot arm.

I bet you could come up with something passable between 2 off-axis gyroscopes, 2 large induction motors (magnet suspended in a coil that vibrates back and forth – can achieve below 1hz - ~300hz vibration) and some more standard vibrators.

This only helps with angular momentum, not with linear momentum.

Is that really a problem? If something hits your sword it's going to make you rotate your wrist, not stop your hand, because it will be blocking the blade and not the handle.

Not if you're using a sword intended for cutting strokes and strike correctly. Distal to the "sweet spot", your hand will continue while the blade is rotated; proximal, and the distal end of the sword will tend to continue while your hand is levered backwards. Just as when using a tennis racket or a baseball bat, though, the moment is balanced around the point of contact when you strike correctly (the proximal part of the blade has more mass but less velocity; the distal has more velocity but less mass) and the blade, as a unit, stops (or is at least slowed by a uniform scale when the target can be cut through). Transitioning from a "chop" to a "slice" requires additional input from the swordsman.
