ABOUT THE ANT: The Extrema Ratio ANT is the most compact of Extrema Ratio's folding knives. It is an extremely robust, durable, and reliable folder in addition to being a compact size. The ANT is easy to carry in a pocket, on a key chain, or in a handbag. In certain areas, a small folding knife is more likely to comply with legal restrictions on the blade length that can be carried. Despite its size, the ANT can handle many everyday tasks effectively, making it a versatile and practical tool for daily use.

BLADE: Is constructed from Böhler N690 steel, hardened to 58 HRC, a steel that achieves the optimal balance between edge retention and strength. The steel is also used in the butchering industry and for surgical instruments. The tang includes a slot for attaching a lanyard or key chain. The blade features a wharncliffe shape with a small slot at the top, designed to aid in easy opening. 

HANDLE: The handle is anodized anticorodal aluminum on a tempered steel frame. The right side of the handle has a clip. Tip up carry.

LOCK: The ANT has a frame lock which is a type of lock used in one-handed knives. This locking system allows you to open and close a knife with one hand. The frame lock is part of the handle itself.*

ADDITIONAL INFORMATION: * Extrema Ratio's explanation of its frame lock. “The handle is made up of two different elements: the grip made of anodized anticorodal aluminum and the tempered steel frame which also performs the function of locking the blade (Frame Lock System). This mechanism requires that part of the frame is folded inwards, firmly fixing the blade in the open position, increasing the operator safety when using the knife.”

NOTE: Extrema Ratio knives, with black/colored finished blades, are designed for many purposes except food preparation. While they are known for their versatility, durability and strength, they are not ideal for preparing food. For food preparation purposes, it's recommended to use kitchen knives specially designed for the task.
