Basically what's in the title: If someone uses a spiky arm guard/bracer (long bracelet type armor not gauntlet) while bashing/battering an opponent (with or without armor) would this result in the wielder breaking their arm or bone or could they do it without harm to themself?
The spiky arm guard/bracer in my mind is made entirely of metal, either bronze or steel, with many similar size spikes surrounding it and another like a spiky mace which has some gaps and fewer spikes also can have different size for each spike. I think maybe a leather arm guard/bracer with metallic spikes would help absorb the impact to reduce harm to the arm upon attacking, or am I wrong?
And another with two layers with the outfacing part having spikes that are a bit loose so a straight or a hook punch can make a twirl or drill like movement to the spike that can chip off the opponent that makes contact with the arm guard.
Some alternative suggestions for design are welcome.

Spiky Mace Type which has some gaps and fewer spikes also can have different size for each spike, just imagine the previous arm guard/bracer above and replace the spike or the pattern with this one. Credit from:
