The shihonage that I worked myself into has me drop center as I enter under the use's arm, as I turn to the outside I stay down, keeping the held wrist/hand circling out and around, with the arm brushing the top of my head as I pivot through. I keep the arm out and extended to keep uke on the edges of their feet and destabilized.... If I dropped further anytime during this motion or just pulled down it would likely result in damage. I take use's wrist/hand right back into their shoulder.....once that is reached I do what some might call a scissors cut.....stand up and bring my hands to my waist as if cutting with a boken. My center rises up as my hands/arms come down to meet. If uke has been destabilized this motion drops them right at my feet with no injuries and without giving them back their center.
