Buck 664 Alpha Field Knife - Richlite

The Buck Alpha Field Knife Pro, a knife built for the rigors of large-game. Field dressing an entire animal? The S35VN steel will hold an edge throughout the process without needing to resharpen. A high-panel flat grind adds strength to the blade that allows you to cut with confidence.

Jimping on the top of the blade gives you the ultimate control when using different grips on the knife for detailed work. The purpose-designed textured handle gives you a trusted grip, even in wet conditions.

Includes a reinforced leather sheath that keeps your knife on your belt or safely in your pack. The Buck Alpha Field Knife is the perfect knife for the Outdoorsman that demands the most out of their equipment.
