At Buck, you'll always find a wide range of knives to choose from. Each knife we bring to market has been thoughtfully designed and engineered. Blending the right properties into stainless steel will ensure that your knife has the right hardness and strength. Heat-treating or tempering the blade helps the knife hold its edge longer and makes it easier for you to re-sharpen the blade. It's the heart and soul of the blade and no one heat treats the way we do.
