Based around superior ATS-34 steel with a Rockwell hardness of 58-C Colonial's USA produced knives offer improved toughness, better edge retention, higher resistance to wear and edge chipping while maintaining ease of sharpening, why? unlike other knife manufactures' Colonial knife pays extra attention to the hardening of each blade to ensure that the proper blade Rockwell hardness is being achieved. It's the ability of knowing how to achieve the proper Rockwell hardness that matters most, not the type of steel being used, whether exotic steel or pig iron, makes no difference if the maker can not or does not know how to reach the proper Rockwell blade hardness, anything less than 58-C, and the blade won't hold an edge and is difficult to re-sharpen. The M-724 S.W.A.T is a USA-made fully-equiped, heavy-duty folder with an automatic ATS-34 with a black non-reflective black oxide coating housed in a linen Iosplast (same mterial used in hardhats, power tools casings and snowboard bindings, its indestructable, please see our You-tube video of our knives being driven over to show their toughness) Despite the 3-inch blade it is relatively lightweight at 1-ounce and slim. It is quick to open and durable. With a push of the button, the blade opens quickly and locks ups with a secure click of the lock, slide the secondary lock into the forward position to extra redundancy. The Isoplast handle offers superior grip in wet or dry condition due to Colonial's patented "Tire traction" design. The handle designed by engineers at the Rhode Island School of Design and Brown University, contours to you hand making it comfortable to grip for long periods. Combining all these features with a thin profile and reversible low-carry pocket clip make it the perfect choice for your every day carry.
