Here goes, the JD Bobben was originally designed by the guy that invented the bick lighter. I really like the design and the style of these Bobins never had one cut the thread. They went out of production. A few years ago they were reintroduced to the market under their name wishbone Bobbin, they were distributed by Hairline. They came into styles long and a short tip. A search of the hairline consumer catalog did not list this product as being distributed by them at this time. I googled them and a few places still list them. Fishin' Jimmy
