You need some REALLY good aim to trap a sword right against the tip of your punching dagger. I don’t think that ever really happens.
There is a European equivalent called the trident dagger and they’re like 30cm wide: https://commons.wikimedia.org/wiki/File:Dague-trident.jpg and they were never really popular because where are you going to put this parrying dagger?
