A MESSAGE FROM THE BUCK FAMILY
If this is your first Buck knife, “welcome aboard.” You are now part of a very large family. We think of each one of our users as a member of the Buck Knives family. Now that you are family, you might want to know a little more about us. The fantastic growth of Buck Knives, Inc. was no accident. From the beginning, we determined to make God the Senior Partner. In a crisis, the problem was turned over to Him, and He hasn’t failed to help us with the answer. Each knife must reflect the integrity of management. If sometimes we fail on our end, because we are human, we find it imperative to do our utmost to make it right. If any of you are troubled or perplexed and looking for answers, may we invite you to look to Him, for God loves you.
