Bicep Slicer Escape
Bicep slicer escape — the one arm submission you straighten out of. Keep the elbow tight so the fulcrum never seats, extend the arm, rotate the elbow to unseat.

The bicep slicer wedges a rigid object — forearm, shin or knee — into the crook of your elbow and folds the arm over it, crushing the muscle and loading the medial elbow. For the attack, see Bicep Slicer. It is the arm version of the calf slicer: same wedge-and-compress mechanic, different limb.
It is the one arm submission you straighten out of. Every other arm attack in the corpus is answered by bending — the straight arm shoulder lock, the Mir lock, the 3/4 armbar all say keep the elbow in and folded. This one needs the fold. Bending into it is the finish, and a defender running the trained arm-defence reflex applies the submission to themselves.
You will meet it mostly in ADCC-style and submission-only contexts. IBJJF restricts it at lower grades, which is worth knowing not for the rules but for the training consequence: many grapplers reach a high level having never had one applied to them, and meet their first one with a reflex that makes it worse.
Elevated RiskBicep Slicer (Defence) is an elevated risk technique. The bicep and brachialis are crushed against a rigid fulcrum while the elbow is forced into flexion around it, so muscle damage and medial elbow loading arrive together. The muscle pain is sharp and immediate and does not track the joint load underneath it — the same signal problem the calf slicer has. The specific added hazard is that the correct defence is the opposite of the trained one for every other arm attack, so defenders frequently increase the load while believing they are escaping. Serious injury can occur Seconds, with muscle pain arriving first and independently of the elbow's structural load..
