I bought my girlfriend, She-Ra: Princess of Power, a purple Brutus the Bulldog keychain to serve as her attacker ass-kicking assistant, but I'll admit when it arrived, it turned out to be a lot bigger and clunkier that I expected, especially with her fat wad of keys looped onto it. Brutus' ears are definitely pointy, and could do some major epidermal and corneal damage, but I'm not sure how quick She-Ra could fish him out and knuckle him up under a threat.
For ladies going solo--whether it be a 10K run or a late-night walk through a parking garage--Fisher Defensive's Go Guarded might be a more convenient, comfortable, and continuously accessible personal safety EDC.
Go Guarded wears like a ring, with adjustable inserts that secure it on fingers sized 7 to 9-1/2. The pink or gray outer layer is a thermoplastic elastomer that provides a soft grip and smooth fit. It covers a sharp, jagged poker of glass-infused heavy duty plastic. When it's time to deliver the money shot, the elastomer naturally bends and folds away from the poker so the latter can strike at full effect.
