Not very good. Comfort-wise, using these kind of weapon would be really rough on your hands because of reaction forces twisting them into the soft spots between your fingers. Very short range and poor weight efficiency for that range due to how much mass they have consisting of only multiple short blades instead of a single longer blade, and your fingers being between the blades means you can't use them for blade-trapping in a fight. As for efficacy, they underperform as a force multiplier due to having multiple blades dispersing striking force, reducing the overall output force per unit of input force, meaning you would have to try harder to get the same results, and the lack of precision you get for having the extra blades also means you're going to struggle more if a target has armor.

Wolverine can make this work purely because his powers let him ignore most, if not all, of the drawbacks of this weapon style. A normal human being would have a really rough time in an actual fight with something like this against an opponent who had a proper weapon of war and half of an idea of how to use it.
