Probably should start with another example since Bob freely encouraged people to make his designs and gave away his patterns and techniques.
On the contrary, I think that is the perfect place to start defining the the parameters of what constitutes "unacceptable" copying of a design.
You seem to believe that this lies outside the parameters of what constitutes "unacceptable" copying of a design. Probably most folks here would agree.
Why? Did Loveless specifically authorize or approve of these particular folks making his design? Is that required? Or did he make a public pronouncement inviting
anyone to use his designs? I don't know - maybe you do. And if he did, does that then define the boundary: can't use a knife design without a dedication to the public by the original designer.
Or is just giving credit to whoever's design you are imitating "good enough?" And what if it is a knife that is never intended to be publicly shown - then how would you even
do that?
And how close does it have to be before it is unacceptable? ALL of these knives include various combinations of elements of earlier knives made by others. How close does it have to be to something else before it is unacceptable?
One could take the position that knifemaking is like any other business in this world, and if you don't want folks copying what you have designed, you need to legally protect it or STFU. In one of my many former lives I used to design two-way radios for Motorola. They had folks on staff who did NOTHING but purchase and dissect radios made by their competitors to see what ideas were incorporated and which ones they could "borrow." And I can assure you that all of their competitors did the same thing. Pretty common (or at least used to be) in electronics. Probably cars, too. It is not like knifemakers have never obtained patents on their designs. We know that they have. Why should someone who went to the trouble and expense to do that be in the same position as someone who did not care or think it was valuable enough for them to do that with their own designs?
Sorry, we do not live in a black and white world, and I do not see this issue as being as "black and white" as some of you seem to think it is.
