When Jillian Holtzmann introduced her fellow Ghostbusters to new sidearm equipment, Erin Gilbert was told to pick any piece of equipment. Erin picked up the Proton Grenade Launcher, but Holtzmann freaked out and told her it wasn't ready. Holtzmann then gave her the Swiss Army Knife. Erin thought it was a proton weapon at first until Holtzmann made it clear it was a regular model and then said, "No woman should walk around unarmed." She gave Erin a Proton Grenade (Air filter version) to test.
Later, Holtzmann, Abby Yates, and Patty Tolan were pinned by the huge Stay Puft balloon. To save them, Erin used the Swiss Army Knife to pop it. Remembering Holtzmann's words, Erin quipped sometimes you only needed a Swiss Army Knife.
- The model given to Erin is the standard Victorinox "Huntsman" knife.
