I totally get the thing about the design. I really hope SRM stops being inspired by other's work, they have potential to come up with their own designs and they have several of those. Also keep in mind that SRM is not the only one who did that. Quite a number of well respected and loved knife manufacturers have done something like this.
Hmmmm..... so when inspiration stops, what do we have? Should all the fine makers of knives quite incorporating the good design features, handle materials, blades steels or ergonomics they like on other knives into their own designs?
No more frame locks? No more liner locks? No more convex edges? No more thumbstuds? No more lanyard holes? No more serrated blades (OK... that wouldn't bother me

) ? No more flat grinds? No more coated blades? No more swedges? No more nail nicks? No more stainless/man made handles?
Should we all be driving model "T"s ? Should be be flying in propeller driven single seat planes?
Where would you draw the line on that statement? Inspiration is the mother of creation. I cannot imagine an author, artist, mathematician, designer, or craftsman that will not readily admit to be inspired by the works of others.
Simply put, inspiration fuels creativity. Creativity is the father of innovation and invention.
No doubt with a bit of inspection one can see the similarities in patterns of a stockman, soddie, English jack, a copperhead, a peanut, a trapper, etc. While they are all the same, they are all different. How about butcher's knives, skinners, fillet knives, etc. Should they quit making those models until they find out the source of their inspiration?
I don't recall seeing STR make a misstep here on the knife evaluation. And I can tell by his description of how he was treated by the guy he mailed his prybar to that he has "been to the rodeo". I would think that if anyone had a bone to pick with that knife as a "copy" or a "knockoff" it would be his axe to grind. But he didn't; he pointed out the many and significant differences and concluded the knife was no copy.
That's good enough for me.
