This is a really nice little knife, what i might call a "hook blade," if i were tempted to describe it. It is a three finger blade about 2" in length, meant to be held through the hole with the middle finger, supported by the index finger and held tight with the thumb upon the jimping on the back side of the blade. Held like this it is incredibly secure, and could concievably deliver devastating strikes if desired. For any purpose other than self defense it seems useless, one could perform tasks like opening a box or cutting a rope, but other than that type of task this knife is really impractical. As a weapon, especialy a last resort type of weapon worn on a neck lanyard, this knife would be supremely capable. The sheath is designed for this, and the blade i sperfect for such a purpose. The blade is well made, satin finished and really rather nice in all regards.
