Over 110 years of experience and craftsmanship, Buck knives use the best materials and state-of-the-art technology to create knives that meet the demands expected of a high quality knife, guaranteed with a forever warranty. Each knife brought 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.
