Keith,
I myself don't see a whole lot of difference..But again, I don't design or make knives, so that's pretty easy for me to say...copying is copying, if you ask me, but it's not my design or my knife or my company.
I am quite thankful, that, aside from a few notable exceptions, the knife community is quite open and helpful, and I fully realize that I benefit greatly from this...there are numerous knives out there that bear a suspicious resemblance to each other, for whatever reason..I think it's just inevitable.
Like I said though, Darrel Ralph, for whatever reason, has not commented on this, and when it really comes down to it, his opinion is about the only one that matters, I would think.
The real problem I had was the fallacious comments from quite a few, the scornful replies, and the piling on..that's what I really had a problem with.
I think this type of behavior is becoming more common, and more acceptable, and it sucks to see it happening.
