ABOUT THE S 2 GOI PUSH DAGGER: The Extrema Ratio S 2 GOI PUSH DAGGER [single edge] is designed with input from Italian Navy Seals. In addition, the S 2 GOI was also developed with major input from survival specialists and martial arts experts. This makes the S 2 GOI an especially well-designed survival, self-defense weapon. Versatile and tough.

BLADE: The S 2 GOI blade has triangular planes converging to create a robust spear point. There is a slot in the blade that you can use as a screw pin shackle wrench. The blade has a serrated area on the spine. A lower section near the sharpened blade has a halyard-cutter.

HANDLE: The Extrema Ratio S 2 GOI handle fits between your index and your middle finger with indentations on the rest of the handle (both sides) for your other fingers. This gives you a very powerful grip. Handle is textured to insure your grip is secure even if your hands are wet or you are wearing gloves. There is a substantial window breaker on the end. There are two lanyard holes in the handle. The handle is slightly angled so it fits comfortably in your hand in a natural position. You can removed this handle so you can use the S 2 GO without it.

SHEATH: Made of Kydex. Has an automatic retention to hold your knife in place. Includes a removable lock for either right or left side. There are multiple lanyard holes around the outer edge. An Extrema Ratio belt clip that is adjustable for different angles is attached to the back. An extension provides a flat-blade screwdriver on the end.
