No silly, order two or more
different knives so that you add to the collection!!!
I sort of thought that was what you meant, but around here one never knows.

I most often buy more than one item because I feel like it makes the shipping cost more reasonable...not a position I could defend strongly, its most likely just an excuse to buy more.
I do wonder sometimes how loud a knifeknut would scream if he bought a $50 knife and the box contained a $500 knife.
Privately he would likely scream and jump for joy. Question is, would he contact the seller to correct the error, or just quietly move on. Ethics are such a pain.
In the end however, most good retailers will make things right and we will just have to grab one of the 750,000,000 EDC's from tthe user collection to deal with the disappointment of not getting knife number 750,000,00

True, in the overall scheme of things it's not a huge deal.
However, I do understand the OPs annoyance. He missed out on a knife that's relatively hard to get at a good price. I would have been annoyed and dissappoited too.
To me, and I think many, a big part of the enjoyment is finding a knife you really want and the anticipation of its arrival. It really sucks when something ruins that part of the fun.
It would appear STP made a reasonable effort to compensate the OP for the error. Maybe they could or should have done a bit more, but really nothing they did would have made the OP happy in this particular case.
I still find it odd that his was not the only example of this happening on the Superhawk item. Something very odd happend there.
