Bicep crush escape
Also known as Bicep Slicer Escape — the canonical term used on this site.
Descriptive — compression of the bicep over a fulcrum
Bicep crush escape is the descriptive name for bicep slicer defence, naming the compression of muscle against bone over a wedge driven into the elbow crook.
Etymology. “Crush” and “slicer” both circulate for this family; the crush form emphasises the compression while the slicer form emphasises the wedge. Neither is more correct, and both are common in no-gi rooms.
Mechanics. A slicer needs a bent joint over a fulcrum, so straightening the arm removes the crook the wedge sits in. That makes this one of the few arm submissions escaped by extending rather than bending — the opposite of the reflex most arm defence installs.
Cross-reference. “Bread cutter defence” is the colloquial name. Full escape coverage on Bicep Slicer Escape.
