There are a handful of power acceleration methods developed by Sonny that form part of the impact weapon skill set of Visayan Corto Kadena Eskrima.
For a style where mass, in the form of the size of the practitioner (Sonny weighed probably about 110lbs) or the weight of the weapon, is limited, timing and relative (between weapon and target) acceleration are king ... along with deception and evasion of course.
Yesterday I was playing with R in the back yard and we were exchanging what we had been working on. We talked about the parts of the style that personally resonate with us as individuals, and R pointed to the Bogsai. The Bogsai is a hugely versatile weapon and the 'fulcrum striking' power acceleration skills that are part of it's usage are certainly R's forte.
Fulcrums are achieved by pulling, pushing and twisting the hands and body relative to each other along the weapon, and with the correct timing can produce short range, high impact power at the tip with a very fast recycle to the next strike.
We worked on some mirroring + weapon manipulation exercises, worked some quite unusual combinations and angles, looked at still points, high, middle and low strikes, and explored climb ups and disengagements across the center line.
