This is another backup knife from Extrema Ratio. Extrema Ratio has taken the popular Scout and modified it to make a version that is classified as a combat version. The Defender DG (Double Guard) has a very slim shape with a fuller (aka “blood drain/groove”) that makes the Defender DG lighter without sacrificing strength. It is an excellent, fixed blade suitable for your self-defense as well as your EDC.


The Defender DG's blade has a clean edge and a narrow profile that ends in a spear point. Its tang extends beyond the handle end to form a lanyard hole. The double guard has a lanyard hole on each side. Very sharp blade.


Lightly textured to give you a good grip. Streamlined and removable. The Defender DG's handle has a distinctive shape that is typical of many Extrema Ratio knives.


The Defender DG sheath is made of Kydex. It is MOLLE compatible. Has four reinforced lanyard holes – two in each side. Automatic retention system. No Belt loop.
