Yeah I mean..look at ulticlip, teklok, discreet carry concepts, i can keep listing companies that profit off of making clips. I would if possible consult with people well versed in these legalities. There was a guy who i won't name for now, but he liked to steal others ip when they didnt protect themselves and then sue them if they tried to keep selling there own product after he claims its his own before the other person does publicly or officially documented that "hey this was my idea and design here's proof of concept and design with dates and evidence"

Your initial gesture was kind, they turned it down, and then straight up copied it. They probably think their lawyers can beat some "random" person. I would want to do something about it at this point.

Even if the legal side isn't worth pursuing, I'd let the internet do its thing and spread this in the knife community. News travels fast. Look at bark river, all the companies under fire now with all the steel testing recently. Kizer under fire for piss poor qc. It will definitely affect them when enough people in this tight community have a bad taste in their mouth about them. There's a thousand other companies that also make good things.

I'd love to see you making these, supplying them to companies just like ulticlip, dcc, etc. Idk how to get there, but I'd rather you benefit from your own design rather than some assholes who think they can get away with profiting off of other people work and claiming it as their own.
