Weighted-knuckle glove

The weighting also distributes the impact in a manner similar to a blackjack, transferring concussive force in the case of a head-strike to cause a knockout.

With a properly executed strike, a person wearing weighted-knuckle gloves can even break glass or concrete without pain or injury.

Weighted-knuckle gloves may be either legal or illegal dependent upon the laws in a specific jurisdiction; however, they are generally considered "less lethal" than brass knuckles.

Section 1 Prevention of Crime Act 1953 creates the offence of possession of an offensive weapon in a public place without "lawful authority or reasonable excuse".

The defence to this section is made on the balance of probabilities (civil burden of proof) that the possessor had "lawful authority or reasonable excuse".

[8] In the Republic of Ireland, weighted-knuckle gloves are classified as offensive weapons and are illegal to manufacture, import, sell, rent or loan.
