Be a dapper zapper with the ZapCane

Also the zap cane may also be restricted in your area, laws on stun devices especially those with a reach (batons, tasers) vary greatly. In most jurisdictions this would likely be considered a stun baton legally. Also the aspect of this openly being a self defence item opens the gate to it simply being considered a club with questionable legality where a cane doesn’t claim self defense giving the bearer plausible deniability.
