Keldran Fuma, while reading a book that was riddled with various animal vs animal combat one of the most enjoyable ones for him with the lock and clashes of the bulls. So this is where the inspiration for the technique was drawn from.
When in a clash with any sort of weapon wither it be a sword, hammer, or even a kunai.

And if they are weak enough could dis-arm them directly or shatter the weapon depending.
