The Black Widow uses a variety of equipment invented by Soviet scientists and technicians, with later improvements by S.H.I.E.L.D. scientists and technicians. She usually wears distinctively shaped bracelets which fire the Widow's Bite electro-static energy blasts that can deliver charges up to 30,000 volts, as well as "Widow's Line" grappling hooks, tear gas pellets, along with a new element introduced during her ongoing series during the "Kiss or Kill" arc called the "Widow's Kiss"; an aerosol instant knock-out gas she has modified. She wears a belt of metallic discs, some with disc-charges containing plastic explosives, others have been shown to be compartments to house other equipment. Her costume consists of synthetic stretch fabric equipped with micro-suction cups on fingers and feet, enabling her to adhere to walls and ceilings. In the 2006 "Homecoming" mini-series, she was seen using knives, unarmed combat, and various firearms, but she has since begun using her bracelets again. While in disguise as Yelena Bolova when infiltrating the then Osborn-sanctioned Thunderbolts during "Dark Reign" she used a specialed multi-lense goggle/head-carapace that demonstrated various technical abilities enhancing vision and communication. Later, she has used a modified gun based on her Widow's Bite wrist cartridge, during her adventures alongside the new Captain America.
