Peter Whittaker Collaboration: Creating the ultimate outdoor knives requires going beyond the factory. To achieve top performance and utility, Buck Knives tapped the mind of world-renowned mountaineer Peter Whittaker. Buck´s outdoor knives are designed primarily for backpackers, campers, and hikers. Buck thought the wisdom of one of the world´s top mountaineer climbers would ensure that its knives pass the most severe tests for function and dependability. Whittaker and his staff of mountain guides provided the insight and field testing, enabling Buck to produce and all-new series of advanced-design outdoor knives.
