I do believe this is the first twisted metal bow I have seen. I found only one ad for it, so I wonder how well, if at all, it sold. Couldn't find a patent either.
Very unusual in that you can shoot it not only left or right handed, but also, front or back and available only in 3 weights of 25, 30 or 35 pounds in either recurve or straight limb configuration. I wonder how that front-back thing works with the recurve?
