You wanna counter the karambit, you need to know it's strength and weaknesses.

Strength: It's really powerful and can easily cut through thick fabric in close range. (Some polices are armed with cut-proof or slash-proof vest, which will be useless against karambit)

Weakness: It's really short, obviously. But more importantly, the user must put one of their finger in the loop.

So, first, clearly, don't get in close range, even if you're a police with the best bullet proof/knife proof vest, they can cut your joints. Use any thing that is long, like a chair, a long stick, ... to keep the attacker away.

Secondly, unlike usual knives and especially balisong, karambit cannot (or really difficult) to turn during fight. Sometimes, when fighting a balisong user, you think you got their arm, but they can turn the balisong around and stab you unexpectedly. This could not be done with karambit. There's an arm grabbing technique in boxing that could be use really effective.

So, that's pretty much it.

Bonus: if anyone've watched karate kid (the one with jackie chan), he used a wrist twisting technique (which you should recheck with a friend)-could loosen the tension of the fingers and make your opponent drop -any- knife.
