A wise commenter will recognize that every consumer item is a blend of objective utility and subjective likability. What one Youtuber calls the first and second kinds of cool.
One makes a serious blunder by conflating the two. That is, just as the subjective cool factor cannot reasonably be characterized as objective functionality, so too one should not make the same mistake you are making. That is, assume that all there is to a knife - or any consumer item - is its functionality. Whether its knives or cars or women, its how they make us feel that matters most. And just because you aren't feeling it, that doesn't mean that no one else should either.
