With its long history and strong reputation, the brand has evolved into the modern day standard for innovative, lightweight, ergonomic, productive and professional tools. We set the standard with our line of premium titanium hand tools that span numerous trades such as framing, remodeling, finish work, siding, demolition, concrete and drywall. Titanium is 45% lighter weight while providing the same striking force and strength as steel. Titanium tools also produce 10 times less recoil shock which helps reduce carpal tunnel syndrome. The combination of these features means less down time, more productivity and most importantly less pain while working.
