No.6 wrench

The No. 6 Wrench, also spelled Number Six Wrench, is an item that appears in Donkey Kong Country 3: Dixie Kong's Double Trouble!. Dixie Kong and Kiddy Kong need to return it to its rightful owner in order to reach the secret cave.

When the Kongs meet Björn in Razor Ridge, he tells them about his broken chairlift, and how he had lost his No. 6 Wrench, which he needs to repair his chairlift. Barter has the No. 6 Wrench at his swap shop, and is willing to trade it to the Kongs for the Mirror. When the Kongs return the No. 6 Wrench to Björn, he fixes his chairlifts and allows the Kongs to use his chairlifts to go up to the world's secret cave, Clifftop Cache.
