As a follow up when the opponent steps over your knee hook foot on Tripod sweep, simply lasso around the leg and expose the heel for a devastating lock. Be very very gentle with this as it tends to do damage BEFORE you feel much happening.

Note that Jen gets on her hip to apply the lock so she has plenty of room to arch with the elbow-hooked heel.

An added variation – if the opponent attempts to roll away, is to drop your instep behind the far leg to tangle that option.

*please don’t play this technique live unless you’re prepared for the consequences!* Great for Self – Defense however!
