Knife fighting is strongly developed in the Filippino martial arts and a great variety of styles can be found. This has a logical explanation. Eskrima was originally developed on the battlefield and contains some very realistic aspects because of that. Hence the highly developed knife fighting because it is always safer to use a weapon in one's defense when a fight occurs uexpectedly. Even if that weapon is a knife.
The training starts with defense techniques against different knife attacks. Many blocking and defense techniques are taught in four ways: single, double and multiple sliding and slicing. Counterattacks are performed simultaneously. More elaborate defence techniques contain locks, disarms and checking and re-directing the opponent's weapon.
The advanced training consists of knife-to-knife techniques taught through a variety of drills containing practical offense, defense and counter techniques in different combinations with continuous checking and re-directing of the opponent's weapon hand.
