The Ronsonator has a great history as it was named after Jon Ronson of the BBC who made the crazy rulers of the world, where Master Brusso was in part 1 of the three part series. Next he became in Playboy then into the book “the men who stare at goats” chapter 8. As an honor to Jon Ronson Master Brusso made this very unique and violent weapon in his honor. Now he doesn’t much like that idea but he had a contest to name it. And in the UK they named it the “ronsonator”. So here it is. Designed to take people out from behind with the points on the bottom and then has two digit breaking places and one soft tissue capture. Beyond fully feathered this thing is just plain nasty. When you need to get the job done this is it. This is one of the most aggressive self defense weapons we have!
