Today I actually found out who did what and such on the original equipment like my box blade and, without naming all of the companies involved, can answer some of the questions on this.
In the days when I bought my box blade, it was designed by company A, manufactured by company B and then marketed by company C under their name.
Now, company B is doing their own marketing and still using the designs from company A. They have, individually and collectively, parted company with company C, which is still marketing attachments under their name which either they manufacture and market themselves or are manufactured by someone else for them to market.
In any event, it seems all three are doing well and life goes on. /forums/images/graemlins/smile.gif I know nothing of this new startup company or what they're doing.
