GATCO Sharpeners

GATCO has been a leading name in sharpening knives, tools and more for over two decades. Every sharpening device is built from quality materials and backed with a tradition of premium customer service.

Great American Tool Company

In 1989, my wife Nancy and I started The Great American Tool Company in Buffalo, New York. Our mission was to manufacture high-performance knife and tool sharpeners and accessories. Today, as we celebrate our 15th year of business, our company and product line have grown, but our philosophy remains the same: to build precise and reliable knives and sharpeners that perform to 100% customer satisfaction.

Our valued customers now include sportsmen, tradesmen, police, military personnel, special operations team members, firefighters, paramedics, first responders, EMT personnel, mechanics, professional chef’s, homemakers and do-it-yourselfers. We strive to provide each with the type of fine quality sharpeners, knives and tools to help make their work more productive, their leisure time more enjoyable. In turn, they give us their continuing patronage for which we are most grateful.

Our long-standing commitment to quality extends to all aspects of our business. You have our promise that the professionals at GATCO® Sharpeners and TIMBERLINE® Knives will continue to provide precision-made, high performance knives, tools and sharpeners, and deliver swift, responsive service and support.
