My brother-in-law Ricky tells this tale about me, which he swears is absolutely true despite my being present when he told it. I tried my best to correct his version. I'm sure it's probably greatly embellished by now, so long after the actual event...
I was teaching a tonfa form to the neighbor’s boy when I was home in 1994 visiting with my sister and her husband. One technique calls for a leap into the air with a 360-degree spin, landing in a defensive position with one tonfa raised to protect the head, and the other aligned to protect the back leg.
I was standing on a slight rise or hillock on the back lawn, and landed (with incorrect placement but safely) in the depressed area in front of the rise and closer to the house. Ricky was watching out the kitchen window. Of course, he had never even seen tonfa before, had no idea they were quite similar to what is used for police batons now, and totally misinterpreted what he saw…
His tale is that I spun the tonfa so fast, I was lifted into the air like a helicopter at least 6 or 7 feet, did a flip, and landed (“light as a feather”) with weapons raised and ready.
Actually, I jumped about a foot or less off the ground; just enough to clear a 360 turn in the air, and landed in the depression facing the house – it may have appeared to Ricky that I was airborne. Frankly, it’s a wonder I didn’t twist an ankle or stumble when I landed. I expected to land on the same spot. Landing forward of my start point and on a lower level lower (about a foot) felt awkward and dangerous. I cautioned the boy to practice on as level a surface as possible.
I explained this all to him, and even tried to duplicate the erroneous feat. He was just more sure that I was either being modest, or hiding my "true Ninja abilities" (I don't practice Ninjutsu, it's karate, for crying out loud!).
I’m not sure about the practicality of the technique, other than to “wow” an audience. I don’t even practice tonfa anymore. I was 23 years (and pounds) younger then.
