Shattering your knuckles sounds like a bad idea, especially if your initial defense does not incapacitate your attacker, as it may render you unable to continue to fight back.
As Despoticun mentioned, a ‘tactical’ style flashlight or pen would be better options.

Fitspacks are always a bad idea. If you want something legal to carry, start keeping your keys on a locking carbiner rated for rock climbing. If it has a kilonewton (kN) rating stamped in it, it is suitable. This won’t collapse on your hand and no amount of force any human is capable of generating will break it, but anyone whose nose you drive it into at maximum effort is likely to remember the experience. This should also be legal to carry anywhere.
