Pro-Grade products are designed and built with one goal in mind - to equip your customer with the best value available in Professional Quality Hand Tools. To ensure long-lasting durability and performance, we start by using only premium quality raw materials like Chrome Vanadium Alloy, Chrome Nickel and High Carbon Tool Steel. We then employ the latest in design innovation and ergonomic styling because a professional quality hand tool should not only work hard, it should look good doing it. Precise manufacturing techniques and strict quality control are then added so that every product will meet or exceed A.N.S.I. (American National Standards Institute) or U.S. Federal Specifications for quality and performance. In fact, we're so sure of our product's quality..
