Ok, update after letting Mime search for solutions with the other servitors:

It's a knife-bomb, really nasty thing, heavy energy used to create it which indicates some serious player. But the bomb trigger also required a strong force to be pulled, so that it could be passed around until a strong enough person tried using it. It seems to have been made as a trap bomb to kill very strong enemies, by releasing a large amount of knives in all directions.

But since this means it contains the magic of the creator and their path, it can also be reverse engineered, so maybe in some backwards way it was arranged by someone as a means to expose this magic form to whoever could expose the trap and disarm it.
