I can't help but think what if it was a Chinese manufacturer making this. Would making a exact copy still be OK?
I'm not sure what you mean, if someone random made an exact copy, it would certainly and quickly be attacked as a clone. Regardless of where they were from, and there would be no debate.
The only reason this one gets any sort of a pass is that everything is above board, save for giving Mr. Pardue any credit. Its not a complete copy, the axis lock is no longer under patent protection and while the Axis name might still be trademarked, they are not calling it that. The blade is generic enough that there is not really a concern there. The clip-screw spacing is kinda odd, but there is enough aftermarket action that it could just be a simpler move, the same thing happened in paintball all the time in the '00s, you'd use one of the standard barrel threadings from one of the big three companies instead of cutting yourself off from the aftermarket. So if/when the main concern is addressed there will likely be no concern remaining. While I don't like a company doing legal minimum redesign, and I think that overall the industry would be better served by giving credit. I think they should have credited McHenry and Williams on the lock design, and I think that Mel should get credit for the overall handle design, this is not as simple as most of the straight up cloner threads. I'm still on the fence, as to the entire ethics of a thing, I'm still of the opinion that Doug is from a different generation and thus doesn't see it the same way as many. I would prefer that they gave full credit as I think its due, and it would only help both companies.
I think that the knife industry as a whole needs to address how credit is given, and how design lineage can be described. When it was a smaller number of designers, things were different, but what happens in 10-20 years? I'd like a new designer to be able to say, I've used a Pardue handle with my own twist, rather than just trying to get to some 51% redesign mark. I also think that part of our role as fans of these designers and makers is to keep those names as part of the collective memory, especially as patents and trademarks expire, we need to keep the flame as it where, and tell newcomers the history.
