The Extrema Ratio Fulcrum 2 is a heavy duty folder that was developed along side an Italian anti-terrorism unit. It was designed to meet specifications that extended its use as a cutting and fighting knife to include the ability to pry. The prying functionality comes from its thick .236″ (6 mm) blade. At a modest length of 3.74″ it is very stout, providing the necessary lateral strength for abusive tasks. The Fulcrum comes in two versions : what Extrema classifies as a drop point and a tanto. The profiles could also be considered having clipped points due to the sharp angle ground from the spine toward the tip. Both versions have a flat primary bevel and steep swedge. The drop point comes in a plain edge while the tanto a partially serrated one.
Although not a graceful slicer, the Fulcrum 2 is still competent for general utility tasks. Where the geometry really excels is in penetrating cuts. The sum of the grinds on both versions terminate at a spike like tip that can be forced through materials easily. The blade has ambidextrous thumb-studs for deployment and a steep, jimped thumb ramp for added control. All versions have a mil-spec black oxide coating.
The tang travels on a fat pivot and against teflon washers. When opened, a heavy back-lock holds the blade firm and without play. This component is also .236″ thick and hinges on a hidden pin. The lock spring is ridged and while it provides excellent security, makes for a resistant deployment. It also snaps the blade shut at about 30º. As a side note it is quite resonant, announcing itself without subtlety.
To ensure the knife stays open in use, there is an additional safety lock that prevents the back lock from disengaging. Extrema mentions that the safety can also be used to keep the knife closed in case it is taken ‘without authorization” by a person who is unfamiliar with the mechanism. This purpose may be easily foiled however as the words “lock” and “unlock” are clearly written on the scales. Perhaps not though, as words are backward from my perspective as you push on the side labelled ‘unlock’ to lock the knife and vice versa. Quirks aside this simple safety works well and is one of the more solid mechanisms I’ve tried. Because of the intended hard use of the knife it is also an appropriate feature.
The butt / back-spacer carries on the same thickness as the blade and back lock. This forms a pointed pommel that can be used as an impact tool or weapon. The utility is greatly enhanced by the thumb ramp as it creates a finger groove when the knife is closed. This part also houses the lock spring, a large lanyard hole and is engraved with a unique serial number.
The thick spine of the knife is held between matte black anodized, aluminum scales. The general shape of the handle is boxy and the surface smooth. To add comfort, all angles are chamfered. There is a finger groove to help with retention that also flares into a front guard. As with the majority of Extrema’s handles, there is a relief milled for the first finger that also allows for easy access to the thumb studs. Although angular in appearance, the grip is comfortable and secure. There is a large tip up ambidextrous pocket clip for carry. The knife has also been designed to easily fit into a pistol magazine pocket.
The handle on the Fulcrum is well thought out and provides good support for the blade. It also has a low part count and simple components that will allow for easy maintenance. The entire assembly is held together with three fasteners, including the pivot (excluding the clip bolts) Extrema includes the two allen keys necessary for adjustments. There are also an extra set of bolts that are inserted in the holes opposite the clip.
Over all the Fulcrum 2 is a stand out folder. Although not a huge knife it is a competent tool with its heavy build and prying capabilities. Co-designed by and geared toward military and law enforcement, the knife would also make a great collectors piece as it is truly one of a kind.
I really only have one criticism of this knife : The giant, garish “Extrema Ratio” and “58HRC Stainless Cobalt Steel” plastered on the primary bevel. I really wish manufacturers would let the blade breathe instead of adding gaudy details and tactless logos where they are not needed. Some might also criticize the weight of 7.05 OZ ( 200 g ) but unlike many folders in this weight category, you are getting much more “pound for pound”.
