A very good question Phil!
The short answer is this. Do you recall the case of the man who invented the ratchet wrench. What we cal a socket wrench. Sears riped him off and brought it out as their invention. He went after them. But just as any small custom shop owner, he didn't have the financial backing to compete with Sears. It took years. When he finally won they appealed. It took decades. By the time he had won, and received his compensation, he was long dead, and died broke fighting The Sears legal Machine.
There are hundreds of cased like this. And to top it off, he was just going after one company! We have been ripped off by a lot of them!

Better to just make Knives. But it doesn't mean it doesn't hurt, or piss us off.
now here is the crazy part. I own several Cold Steel Knives. In fact, I'm trying to get my hands on a bowie prototype ground by Jim Merritt him self. (Loveless Partner) Yep, He worked for CS for a while.

Years ago. All this stuff isn't new. Just is to the newbies.
