DMP is a multi-role knife characterized by a strong versatility of use thanks to the small dimensions. The blade, drop point shape with reinforced tip, is particularly useful for heavy duty use. The full flat rounding gives excellent cutting characteristics.

The sheath is minimalist, stripped of most of the fabric adopting a retention system of 2nd level, going to recall the style of the model to which it is inspired. The main shell is made by injection in shockproof nylon. The secondary retention system is reversible for the ambidextrous portability of the knife.

After the success of the FULCRUM multirole knife, the civil bayonet version NFG (No Fixing Gears, without rifle attachment) was born. Like the FULCRUM, the bayonet is an extremely robust and versatile knife, the blade withstands breaking loads exceeding 150 kg, the tip is very robust and the profile allows you to work for a long time with the knife without affecting the sharpness of the last section . The advanced center of gravity and the weight of the blade make it suitable for heavy field work.

Extrema Ratio developed the first knife of a new production line, called CONTACT.

It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect itself from incidental cuts, upper jumping to improve grip, concave fuller along the length of the blade and a generous thickness blade (6.30mm) the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.

The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colors in production have got a blade with Stone Washed finishing. The handle is still in forprene. It is more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided through the conception of the blade. To extract the blade, to pressure the trigger will be sufficient, thus releasing the safety that holds securely in the sheath. In the horizontal slits of the sheath of a system, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.

The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop Extrema Ratio aims to reduce the size of the knife, but not saving on the structural strength and safety accessories.
