Does Buck offer factory tours?
Yes. Our tour is a great opportunity to see how Buck knives are made. Tours are offered year-round, except during holidays and when the factory is closed for vacation or maintenance (please call ahead to check our schedule and make reservations). Tours are free of charge and are given Monday through Thursday at 10 am, 12 pm and 2 pm Pacific Time. Tours last about 25 minutes. Closed-toe shoes are required (no exceptions). Children must be at least 7 years of age. Tour hot line is (800) 326-2825 x 270. For address/directions, please click on Plant Tour.
