Extrema Ratio Pocket Knives

Extrema Ratio folding knives combine military durability and simple civilian functionality. Initially, the brand, founded in 1997 in Italy, developed knives for special forces. Almost all Extrema Ratio folding knives are made using high-quality Böhler N690 steel and anodized aluminum. Some models use M390 steel. Among the popular series of folding knives are:

- BF (Basic Folder): Compact and lightweight knives such as BF1 and BF2 are ideal for everyday use.

- BD2 and BD4 are tactical folding knives with a double guard. Contractor versions are equipped with double-edged blades.

- MF (Medium Folder): Models MF1 and MF2 are designed for tactical tasks and can replace a knife with a fixed blade in functionality. Equipped with a glass breaker and a reversible clip.

- MF1 Evo — an updated series with an improved Hidden Lock and blades made of M390/N690 steel.

- Ant — compact EDC knives with a 5 cm blade, popular for everyday carry.

- RAO - Powerful knives with a unique locking system, designed for heavy tactical tasks.

Many series of Extrema Ratio folding knives feature special rescue versions designed for use in extreme conditions. All knives are equipped with pocket clips that can be rearranged to a convenient side. Most series feature knives with Spear Point, Drop point and Sheepfoot profiles. Extrema Ratio provides a lifetime warranty on its folding knives. Our store is an official dealer of Extrema Ratio.
