Licensed or is this just theft?
If it looks like a duck and quacks like a duck, it's a duck.The latter IMO, although they would disagree and claim a product developed "in house".
Really... that long. I've been a designer and design engineer for all of my working life. It is heart breaking when the far east, or anyone else, steal designs. I was asked by a customer to copy the Yost offset barebow weight a few weeks ago. It is easy to copy but it's not my design so I refused to make it, whether protected or not.Inevitable and surprised it has taken so long - 11 years...
