About locks and bars

Intro

Locks and bars may seem to be two separate methods of control but sometimes it is difficult to tell one from the other.

Locks are holds where the attacker's arms and/or legs entangle the opponent in such a way that they lock into position and immobilize the opponent so he or she may no longer cause harm. Locks make it difficult for an opponent to resist or escap.

Bars are holds that hyperextend or hyper rotate joints to cause pain to cause submission, to cause compliance, or to damage or break the joint so it may no longer be used

Sometimes locks involve also using a bar and sometimes you need a lock to make the bar more effective.

Locks and bars

Locks can be used to compress a bone against muscle or another bone to cause pain and possibly injury. Some examples are:
  • Achilles lock. A lock that applies pressure to the Achilles tendon.
  • Bicep slicer. A lock that puts pressure on the bicep.
  • Leg slicer. A compression lock applied to the thigh muscle and/or calf.
Locks can be used to compress the abdomen or chest to restrict or stop breathing to cause unconsciousness or death.

Locks can be used to on the neck to restrict or stop blood flow through one or both cardioid arteries, much like a strangle, to cause unconsciousness or death.

Some examples of locks and bars are:
  • Armbar. An arm lock that hyperextends the elbow
